About Colloidal Silver Nano Silver Solution:
Nano Silver solution is a metallic Silver elemental with a particle size of 1-100nm. The particle size of the nanosilver is mostly about 20 nanometers, and a few can reach less than 5 nanometers. With a broad spectrum of bactericidal effects, about 650 kinds of bacteria, and do not produce drug resistance. Animal experiments showed that even if the dosage of nano-silver antibacterial powder reached thousands of times aboutthe standard dosage, the tested animals had no toxic performance. At the same time, it can also promote the repair of damaged epithelial cells. It is worth mentioning that the antibacterial effect of this product is increasingly enhanced when it meets water, which is more conducive to the treatment of diseases.
Nano-silver acting on cell membrane proteins can directly destroy bacterial cell membrane and oxygen metabolism enzyme (-SH), block bacteria and other microorganisms from the absorption of amino acids, uracil and other essential nutrients for growth, thus inhibiting their growth. This unique mechanism can kill most bacteria, fungi and other microorganisms. Nano-silver particles have super permeability and can quickly penetrate into the subcutaneous 2mm to sterilize, which has a good bactericidal effect on the deep tissue infection caused by common bacteria, stubborn bacteria, drug-resistant bacteria and fungi.

About Scandium Metal Sc Metal:
Scandium is a chemical element with the element symbol Sc and an atomic number of 21. Is scandium a metal? A silvery metal that tarnishes in air, burns easily and reacts with water. Scandium is mainly used for research purposes. It has, however, great potential because it has almost as low a density as aluminum and a much higher melting point. Elemental is a soft, silvery-white transition metal, often mixed with gadolinium, erbium and other existence, the yield is very small, in the earth’s crust content is about 0.0005%. Why is scandium so expensive? Owing to its scarcity and limited production, scandium is one of the most expensive of all the natural elements.
Is scandium harmful to humans? Health effects of scandium: Scandium is most dangerous in the working environment, due to the fact that damps and gasses can be inhaled with air. This can cause lung embolisms, especially during long-term exposure. Scandium can be a threat to the liver when it accumulates in the human body.
Scandium is commonly used to make special glass, light and high-temperature resistant alloys. Scandium is slightly yellowish or pink when oxidized by air, is easily weathered and slowly dissolves in most dilute acids. However, in strong acids, the surface tends to form an impermeable passivation layer, so it does not react with a 1:1 mixture of nitric acid (HNO3) and hydrofluoric acid (HF). Tqhp is a trusted global Scandium Metal Sc Metal supplier. Feel free to send an inquiry about the latest price of Scandium Metal Sc Metal at any time.
Product Performance of Scandium Metal Sc Metal CAS 7440-20-2 :
The scandium metal is silver-white, generally distilling crystalline lump (meat-like) metal, and the ingot, sponge block or lens can also be button-shaped as-cast with a clean surface. It has a melting point of 1541 °C and a boiling point of 2831 °C. Scandium metal is easy to dissolve in water and can interact with hot water, making it easy to darken in the air.
Technical Parameter of Scandium Metal Sc Metal :
|Product Name||MF||Purity||Particle Size||Molecular Weight||Density||Color|
|Scandium Metal||Sc||99.9%- 99.999%||100 mesh||44.956||2.985 g/cm3||Silver White |
How is Scandium Metal Sc Metal Produced?
The pure yield of scandium can reach 94%, the crude scandium contains 92% of scandium, the main impurity Ta_7 ~ 8%, Ca 0.5%. The use times of tantalum crucible were increased by this method. Pure scandium can be prepared by distilling the crude scandium obtained by reduction in a tantalum crucible with a thickness of 1 mm and a diameter of 40 mm. Ta in scandium can be reduced to 0.02%, and the purity of scandium is greater than 99%.
Applications of Scandium Metal Sc Metal:
Scandium is used in aluminum-scandium alloys for aerospace industry components and for sports equipment such as bicycle frames, fishing rods, golf iron shafts and baseball bats. Scandium iodide is used in mercury vapor lamps, which are used to replicate sunlight in studios for the film and television industry. What is scandium used for in the world?
Scandium sodium lamp has the characteristics of high luminous efficiency, good light color, power saving, long service life and strong ability to break fog so that it can be widely used in television camera and square, stadium, street lighting, known as the third generation of the light source. In the metal-insulator-semiconductor silicon photocell and solar cell, scandium is the best barrier metal.
Scandium, in its elemental form, has been widely used in the doping of aluminum alloys. As long as a few thousandths of scandium is added to aluminum, a new phase of Al3Sc will be formed, which will have metamorphism on aluminum alloy and make the structure and properties of the alloy change significantly. The addition of 0.2%~0.4% Sc can increase the recrystallization temperature of the alloy by 150~200℃, and the high-temperature strength, structural stability, welding property and corrosion resistance are obviously improved and can avoid the embrittlement phenomenon which is easy to occur in the long-term working at high temperature.
To change the agent
Scandium is also an excellent iron modifier. A small amount of Scandium can significantly improve the strength and hardness of cast iron. In addition, scandium can also be used as an additive in high-temperature tungsten and chromium alloys.
The elemental scandium is generally used in alloys, and the oxide of scandium also plays an important role in ceramic materials. Tetragonal zirconia ceramics, such as those that can be used as electrode materials for solid oxide fuel cells, have a very special property in which the conductance of this electrolyte increases with temperature and oxygen concentration in the environment.
The catalytic chemistry
In the chemical industry, scandium is often used as a catalyst, SC2O3 can be used for ethanol or isopropanol dehydration and deoxygenation, acetic acid decomposition, from CO and H2 ethylene and so on. The Pt-Al catalyst containing SC2O3 is used as an important catalyst in the hydrogenation purification and refining process of heavy oil in the petrochemical industry.
Nuclear power industry
Adding a small amount of SC2O3 to UO2 in high-temperature reactor nuclear fuel can avoid lattice transition, volume increase and crack caused by UO2 to U3O8 conversion.
A fuel cell
Similarly, the addition of 2.5%~25% scandium in the nickel base battery will increase the service life.
In agriculture, corn, beet, pea, wheat, sunflower and other seeds can be treated with scandium sulfate (the concentration is generally 10-3~10-8mol/L, different plants will be different). The actual effect of promoting germination has been achieved. After 8 hours, the dry weight of root and bud is increased by 37% and 78%, respectively, compared with that of seedlings.
Storage Condition of Scandium Metal Sc Metal :
The damp reunion will affect Sc metal dispersion performance and using effects, therefore, scandium metal should be sealed in vacuum packing and stored in a cool and dry room, the scandium metal can not be exposure to air. In addition, the scandium metal should be avoided under stress.

About High Purity Graphite Powder Flake Graphite C Powder:
The graphite crystals of natural flake graphite are scaly. They are transformed under high-intensity pressure and are divided into large-scale and fine-scale. It is one of the best flotation ore in nature, and high-grade graphite concentrate can be obtained through multiple grinding and selection. The floatability, lubricity and plasticity of this type of graphite are better than other types of graphite. Therefore, it has the greatest industrial value. The required pressure is usually greater than 1 gigapascal (75,000 psi), and the required temperature is usually greater than 750 degrees Celsius (1,380 F).
Since carbon deposits form natural flake graphite when they are under pressure and temperature, graphite is most commonly found in metamorphic rocks, and the deposits are fairly evenly distributed throughout the rock. Graphite has large flakes, large flakes, medium flakes and fine flakes. The graphite powder price is much cheaper.
Depending on the application, the purity and/or size of natural flake graphite may be more important.
