About Aluminum Al Powder:
Aluminum powder, commonly known as “silver powder”, is a silver metallic pigment. It is made by adding a small amount of lubricant to pure aluminum foil, crushing it into scaly powder, and polishing it. The aluminum powder is light in weight, high in floating power, strong in hiding power, and good in reflecting light and heat. After treatment, it can also become non-floating aluminum powder.
Aluminum powder can be used to produce many types of explosives and fireworks. It is also used in the manufacture of certain types of electronic products. Many coatings and sealants contain aluminum powder. Certain products designed to carry current, such as solar cells, are usually made of aluminum powder. Rocket fuel is usually made of aluminum, and many solid rocket fuels are based on chemical reactions involving this metal.
Aluminum powder is present in various products from sunscreen to lightweight concrete to solar panels. It is produced by melting aluminum ingots in a gas furnace and spraying molten metal under high pressure into fine granular powders. . Depending on the atomizing gas used to “blow” molten aluminum from the nozzle head, two types of powder can be produced from this process.
The applications of aluminum pigments range from graphic arts and inks to automotive coatings and protective coatings for bridges and buildings. The pigments are made of aluminum powder, almost all of which are made through a wet milling process. Put mineral spirits, an acid lubricant and aluminum powder in the mill. When the mill rotates, the balls in the rotating chamber cascade the aluminum paste in such a way that it flattens out upon impact and breaks the resulting flakes.

 How is Aluminum Al Powder produced? 
1. Melt extrusion method
The method is to heat and extrude the remaining components (resin, etc.) of the metallic pigment and powder coating through a screw extruder. Although metallic pigments and powder coatings can be completely mixed, the selection of metallic pigments in high-viscosity melts is insufficient. In addition, the metallic effect of the metal powder produced by this method is gray during construction. Therefore, this method is only used to produce hammer powder.
2. Dry blending method
The method is to add the metal pigment dry powder into the pulverized powder coating and mix it with a mechanical mixer. The advantage of the dry blending method is that the mixing of metallic pigments and powder coatings is not very intense, thereby preventing the deformation of the flake metallic pigments, and the metallic effect will not be affected. In addition, the loose pigment/resin mixture is also very conducive to the option of metallic pigments and improves the glitter effect. The disadvantage of this method is that when automatic spraying equipment is used to process the recycled powder, there is a big difference in the shape, density, and carbides of the metallic pigment and resin powder particles, resulting in separation.
3. Supplementary fixing method (bonding process)
In this method, the metal pigment and powder coating are dry-mixed at the same time and heated at the same time, so that the temperature just exceeds the softening point of the resin. At this time, the metal pigment can be fixed on the surface of the adhesive resin powder to prevent the powder from being constructed. The separation of metallic pigment and resin powder during recycling after neutralization construction. It is the popular bonding law.
4. Jet milling method
This method is produced using the principle of supersonic airflow pulverization. Because the aluminum powder is easy to oxidize, it is generally produced by using the JZDB series nitrogen shielded airflow pulverization classifier to produce an ultrafine aluminum powder.

Application direction of Aluminum Al powder:
Aluminum is a metal element in the crust of bauxite. Aluminum is extracted from bauxite and then separated using a chemical method called the Bayer process. Aluminum is a soft and easy-to-shape silver medal and is non-toxic and non-magnetic. Aluminum is available in both solid and powder form and has a wide range of uses on both commercial and personal levels.
Explosive
Aluminum powder is extremely flammable, so one of the most common uses is in pyrotechnic displays. The aluminum powder burns very brightly and produces different flashing effects in the firework show by using different grades of powder. It is also used in a similar way to the explosive composition used in commercial mining. In the past, when photography was still in its infancy, the aluminum powder was also used to make camera flashes.
Paint
Aluminum powder is often used to make metallic silver pigments and is sometimes sold as aluminum bronze in art shops. Aluminum bronze is flake aluminum powder, usually coated with talc or other compounds that reduce its reactivity. Pigments made from aluminum powder are commonly used as coatings in the electronics, packaging and automotive industries. Aluminum powder can also be used to produce thick pastes, which are then coated on the back of photovoltaic solar cells to make them conductive.
Fingerprint powder
Aluminum powder is often used at crime scenes to form potential fingerprints on smooth, non-porous surfaces. According to the British Home Office, aluminum flake powder is the most effective fingerprint powder used on glass. Except for silver, when used on most colored surfaces, aluminum flake powder can provide good contrast. In order to form a print, a small amount of aluminum powder is applied to the surface with a “Zephyr” brush made of fine glass filament, and the aluminum particles adhere to the print and make it visible.
Rocket fuel
Aluminum powder is an important component of solid propellant used in missile and rocket fuel. The easy availability of aluminum powder, coupled with its high reactivity and flammability, means that when used as a solid fuel, it can be used in large quantities, providing a large amount of thrust at a relatively low cost. A well-known example of aluminum powder used in this way is the reusable solid rocket motor of the NASA space shuttle.

About Nickel Ni powder:
Nickel powder is a gray or gray-black powder with the chemical formula Ni. It is conductive, insoluble in water, ammonia, and concentrated nitric acid. It can reduce nitric acid and finely pulverize hydrochloric acid and sulfuric acid.
 
Nickel powder is divided into carbonyl nickel powder, which is mainly used for coatings and plastics as conductive pigments to shield electromagnetic drying involving radiofrequency coupling, as a variety of high-gloss decorative paints and plastics, instead of aluminum powder as anti-corrosion paint in water-based systems, etc., fine particle spherical Nickel powder can be used for conductive inks.
 
Metallic pigments with metallic nickel as the main component, including nickel powder and flake nickel powder. The former uses distilled and purified carbonyl nickel [Ni(CO)4] vapor to decompose. By controlling the temperature, carbon monoxide is used instead of gas additives. Nickel particles of appropriate size are formed in the presence of reagents (oxygen and nitrogen), and then carbon monoxide is flushed with carbon dioxide gas and the surface oxygen content of the particles is controlled to 0.065%; usually, high-purity nickel carbonyl powder is used in the presence of a suitable volume and liquid medium Next, use steel balls to grind in a ball mill to form flakes of appropriate thickness.
 
Nickel is a chemical element, its symbol is Ni, and its atomic number is 28. It is a silvery-white shiny metal with a light golden color. Nickel is a transition metal, hard and ductile. The powdered pure nickel powder has the largest reaction surface area and can exhibit significant chemical activity. However, under standard conditions, larger nickel flakes react more slowly with air. This is because an oxide layer is formed on the surface and prevents further corrosion (passivation). Even so, only a very small amount of pure natural nickel can be found in the earth’s crust, usually in ultramafic rocks and inside larger nickel-iron meteorites that are not exposed to oxygen outside the earth’s atmosphere.
 
Nickel is one of the four elements that are ferromagnetic at room temperature (the other elements are iron, cobalt, and grams). Alnico permanent magnets based in part on nickel have medium strength between iron-based permanent magnets and rare earth magnets. In modern times, metals have value mainly in alloys. Stainless steel accounts for approximately 68% of the world’s total output. Another 10% is used for nickel-based and copper-based alloys, 7% is used for alloy steel, 3% is used for casting, 9% is used for electroplating, and 4% is used for other applications, including the fast-growing battery industry. In the vehicle. As a compound, nickel has many special chemical manufacturing applications, such as catalysts for hydrogenation, cathodes for batteries, pigments and metal surface treatments. Nickel is an essential nutrient for certain microorganisms and plants that have enzymes with nickel as the active site. Feel free to send an inquiry to get the latest price if you would like to buy Nickel Ni powder in bulk.

Features of Nickel Ni powder CAS 7440-02-0:
English name: nickel powder; nickel flak powder
Molecular formula: Ni
Properties: Gray irregular powder, easy to oxidize in moist air.

How is Nickel Ni powder produced?
Nickel powder can be produced in a few different ways and the process chosen depends on the size of particles and morphology required. One of the most common ways to make nickel powder is the nickel carbonyl process. This process, also known as the Mond process, is used to produce powders with controlled morphology and tolerances. The nickel carbonyl process is also used to refine impure nickel. Solid nickel reacts with carbon monoxide to form nickel carbonyl gas. The gaseous mixture is further heated resulting in decomposition of the metal-carbonyl complex to produce pure nickel metal and carbon monoxide gas.  Fine and extra fine nickel powders can be produced by thermal shock decomposition.  
 
Another method to produce nickel powders is using electrolysis or electrowinning.  This process involves passing an electrical current through an electrolyte containing dissolved nickel metal and allowing the nickel powder to form on the cathode.  Powders formed in this way are known as electrolytic metal powders and are often very dendritic with complex morphology and hence very conductive.  The particle size and morphology can be controlled by varying certain operating parameters and using additives that affect the deposition of the powder onto the cathode.  

Applications of Nickel Ni powder:
Nickel powder is a black shiny metal powder, which is hard and malleable. In the past few decades, ultra-fine powders and nano-powders due to their special characteristics (such as magnetism, heat resistance, chemical activity, high surface area, better reactivity, enhanced hardness, semiconductor conditions and high chemical activity) And it has been improved. Get a lot of attention. Worldwide, pure nickel is also widely used in coinage systems, sonar and ultrasonic equipment.
 
There are many nickel-based alloys, such as nickel-based superalloys, nickel-based corrosion-resistant alloys, nickel-based wear-resistant alloys, nickel-based precision alloys, nickel-based shape memory alloys and hydrogen storage alloys. These alloys are used in the aerospace industry, automobiles, electronics, shipbuilding and many other fields. Nickel powder is used in powder metallurgy alloys.
 
Introduction of nickel powder for diamond tools (metal-based alloy powder): Metal belt is one of the key factors that determine the quality of diamond saw blades, cutter heads, grinding wheels, thin-wall drill bits and other products. After determining the diamond, the quality of the metal bond is the decisive factor. Both cobalt powder and nickel powder can be used as the main binder, but the price of cobalt powder is higher.
 
In diamond tools, the matrix refers to the packaging, the metal sintered body of diamond, the matrix is usually composed of a variety of metal elements, mainly using low melting point metal powder as a binder, such as nickel powder.
 
Most of the matrix bonding materials for diamond thin-wall drill bits and cutting discs used in the construction industry, oil and gas and other mining diamond drill bits, and carbide drill bits use nickel powder.
 
For metal material processing, most of the tools used for the mechanical grinding of automobiles and motorcycles use diamond abrasives, and most of the matrix materials also use nickel powder. Including carbonyl nickel powder, electrolytic nickel powder and reduced nickel powder.

How is Chromium Cr Powder produced?
In the production of chromium, the calcination process of chromite calcium is used to convert chromium trioxide into sodium chromate, which is leached into sodium chromate solution with dilute solution and water, and then manufactured by electrolysis method.
Electrolysis method: when sodium chromate is used as compensation solution for electrolysis, the cathode solution is 40g/L(Cr), 90g/L (NH4);Anodic solution is 22g/L (Cr), 18g/L (NH4), 200g/ LH2S04.Chromium metal was prepared by electrolysis of stainless steel for cathode and Pb-Ag alloy for anode at the temperature of about 60℃, cell voltage of 4.8V and current density of 8.6A/CrR12. Due to the high content of silicon, aluminum and other impurities in chromite and its additive, the amount of slag discharged in the process is large, because the slag contains toxic water-soluble Cr6+, which seriously pollutes the environment.
The process developed in recent years: the chromite is first reduced by carbon into carbon ferrochrome, and then oxidized by roasting and leaching with soda ash, dolomite and other mixtures to obtain sodium chromate solution, which is reduced by sulfur and calcined to obtain chromium oxide, and then smelted, sandblasted and finished with aluminum to obtain metal chromium products. The advantage of this method is that most of the impurities in chromite enter the smelting slag, so the total chromium in the mixture can be higher, and the pollution to the environment can be reduced, and the soda ash consumed in the roasting process is less, and the quality of the products can be improved at the same time.
 
Applications of Chromium Cr Powder:
Chromium powder uses are very wide. Chromium powder can be used as light-resistant, the heat-resistant coating also can be used as abrasives, glass, ceramic colorant, chemical synthesis of catalyst.
