Zinc sulfide
This powder is white to off-white, or light yellow in color. It becomes darker as it is viewed. Zinc sulfuride is stable in dry conditions, but if left in humid or moist air for long periods of time, it will oxidize to zinc oxide.
Zinc sulfide powder properties
Zinc sulfuride is an organic compound with the chemical composition ZnS. Zinc sulfide will slowly oxidize if it is placed in moist air or is moistened. Zinc sulfide can be found in sphalerite. However, it is not soluble or soluble when it comes into contact with water.
Zinc sulfuride becomes crystals when it is burned in H2S. The a variation is a colorless hexagonal crystal having a density 3.99g/cm3 at a melting point of 1750°C. The b variant, which has a density 4.102g/cm3, is transformed to the a variety at 1020°C.
Zinc sulfuride is usually obtained through the action of hydrogen Sulfide and zinc Salt Solution. A small amount of Cu Mn, Ag can be added to activate the crystalline ZnS and it will emit different colors of fluorescence when illuminated.
Zinc Sulfide Powder Application
Zinc sulfuride is used for analytical reagents, phosphor matrix and photoconductor material. It is also used in dyes, paints pigments, glass and curing oil.
Zinc sulfuride is easy to dissolve and not agglomerate. It is also neutral white and has great optical properties. It is commonly used as a component in thermosetting plastics.
It is often used to make ceramics due to its good sintering qualities. Studies have shown that monodisperse Zinc Sulfide Powder has a better sintering result than agglomerate Zinc Sulfide. Furthermore, the particle size is affected and can be increased to improve the sintering performance.
Nano-zinc sulfuride is a photonic materials. It can generate photon hole. The energy level change as well as the wider energy gap caused by the quantum effect, enhance the redox capability of this material. It is a photocatalytic semiconductor that excels in this role.
Zinc sulfuride is an infrared-optical material. It has high infrared transmittance, excellent optical and mechanical performance and thermal comprehensive performance within the 8-12ym and 3-5p.m bands. It is the best dual band infrared observation window available for aircraft and hoods.

Or Iron Carbid is a mixture of iron, carbon, or, more precisely, an intermediate transitional metal carbide having the molecular formula F3C. It weighs 6.67% and 93.3% respectively. It is a gray-white crystal powder with a relative density of 7.694. It is insoluble when dissolved in hot, cold water and dilute acid. But it is soluble in hot concentrated hydrogen chloric acid to make mixtures with hydrogen, methane and other complex hydrocarbons. Do not react with dry oxygen. Iron oxide and carbon can be formed by oxidizing in moist air. It has an orthorhombic structure. It is a soft and fragile material and, in its natural form, is classified as ceramic. This is why it is an integral part of black metalurgisty.
What does Fe3C mean?
Cementite also contains Fe3C, iron carbide.
How do you make cementite?
Primary cementite
When the liquid alloy of iron-carbon alloy (hypereutectic yellow cast iron), is cooled below the liquidus, the cementite precipitates.
Eutectic cemented cementite:
The ledeburite structure has a point strip cementite that is uniformly distributed in the austenite matrix. This is called eutectic or eutectic cemite.
Preeutectoid phase, cementite:
Alloys with hypoeutectoid/hypereutectoid composition are always precipitated with a decrease in temperature. This is the proeutectoid Phase. Because of the differences in forming conditions, proeutectoid morphology can be divided into three types, block, reticulate, and Widmanstatten structures.
Eutectoid cementite:
Eutectoid cementite refers to the cementite found in pearlite.
Secondary cementite
When iron-carbon alloys are slow cooled, such as hypoeutectic iron, hypoeutectic iron cast iron, and hypereutectic iron cast iron), the carbon content in austenite becomes saturated. The cementite will then precipitate along austenite’s grain boundary, with a network distribution in microstructure. Secondary cementite is the cementite formed from austenite.
Tertiary cementedite:
When the equilibrium cooling temperature of industrial pure iron drops below the solid solution line for carbon in iron (FeC equilibrium diagram Q line), then the solubility in carbon in ferrite reaches saturation. The temperature decreases again and the tertiary cemented from ferrite. The tertiary ferrite cementite is precipitated from the ferrite-grain boundary. It generally occurs intermittently along the line of ferrite grain border because it is so small.
It refers only to those that exist outside of the mechanical mixture (structure), such a pearlite (eutectoid) or ledeburite.

cr3c2 is a low-melting-point inorganic material with excellent wear resistance, corrosion resistance and resistivity to oxidation at high temperature. It is mainly used as thermal spray materials for surface protection of metal parts and alloys, to refine the crystal structure of cemented carbide and as a coating additive to increase wear and corrosion resistance.
Typical applications include hydraulic cylinders as a hard chrome alternative for wear protection, and metal surface finishing in the manufacturing of components. This chromium carbide powder is sprayed onto metal surfaces using flame, plasma, or HVOF (high velocity oxy-fuel) spray techniques to produce coatings that have excellent resistance to elevated temperature erosion and sliding wear.
Chromic carbides have unique properties that are derived from their chemical structure. Unlike TiC, all chromium carbides have lower melting points than pure chromium and possess a combination of metallic, ionic and covalent bonding characteristics.
In addition, all chromium carbides have a different crystalline structure and a variety of different bonding mechanisms. This is due to the different degrees of ionic and metallic bonding between chromium and its oxides.
For example, the h-CrC phase has a higher ionic bonding than the c-CrC and WC phases and a different electronegativity difference. It is more brittle than the c-CrC phase and exhibits lower elastic constants and elastic anisotropies than the other carbides.
The WC-10Co cemented carbides modified with different mass fractions of cr3c2 up to 1.5 wt% have a two-fold effect on their properties: the adsorption of the additive determines a decrease of the grain size and the formation of the M7C3 carbide, a hard and brittle phase that increases the bulk hardness and the abrasion resistance. Above the 1.5 wt% of cr3c2, however, the hardness of the binder increases and the volume loss decreases.

titanium nitride melting point
titanium nitride melting point, also known as TiN-x, is an inorganic compound composed of titanium and nitrogen. It is characterized by a high melting point, high hardness, good thermal conductivity and chemical stability, and it can be used in high-temperature structural materials.
TiN can be prepared by nitriding titanium metal with carbon, methane, or nitrogen in an air-tight container. It is widely used in the manufacturing of titanium alloys, ceramics and semiconducting instruments.
Nanocrystalline titanium nitride can be synthesized by a convenient process that fully mixes titanium dioxide and carbon powder in proportion. The mixture is heated to 650 degC in an autoclave, where it is converted into cubic titanium nitride.
In electronics, TiN can be used to create conductive barriers between a metal gate dielectric (e.g., HfSiO) and a silicon substrate, in order to improve transistor performance by lowering the leakage current or drive current, while maintaining the same threshold voltage. Thin films of TiN can also be used in copper-based chips, to prevent diffusion of metal into the silicon substrate.
Titanium nitride coatings can be applied on the edges of mechanical molds to prevent corrosion and increase the life of such tools. It is also used in jewelry, medical equipment and the automobile industry as a coating for aluminum and steel parts that require high wear resistance and lubricity.
Titanium nitride is also biocompatible and can be used to make orthopedic prostheses and other surgical tools. It does not react with body fluids, thereby protecting the health of the users.

What is an Aluminium-Silicon Alloy ? Silicon alloy is made up of silicon and alm. It can preserve the exceptional properties of each.
Silicon is an excellent choice for metal alloys that are used for casting. Because of its fluidity and melting temperature, it reduces shrinkage, solidification time, and is inexpensive as a raw material. Silicon is also very dense (2.34g/cm3). This may help reduce the total weight of the parts being cast. It is very solubilized in aluminum. Therefore, silicon precipitates in the form almost pure silicon. This makes it more wear-resistant. This material is rich in silicon and aluminum, and has a mature preparation technology.
Si-Al alloy has a density of between 2.4g/cm3 & 2.7g/cm3, and a coefficient of thermal extension (CTE) of between 7-20ppm/. Si-Al alloy’s density and thermal expansion factor decrease with increasing silicon content. Si-Al alloy has great properties like good thermal conductivity and high specific strength. It can also be coated with gold, silver or copper. Si-Al alloy can be weldable with substrate and allows for easy precision machining.
Silicon-aluminum alloy is a promising option for electronic packaging materials, especially in high tech fields like aerospace, space technology, portable electronic devices, and other high-tech industries.

sodium hydrogen sulfate, also known as bisulfate of soda or sodium acid sulfate, is a dry mineral acid that is commonly used to lower the pH of liquids. It can be found in a number of products, including toilet bowl cleaners, detergents, and dishwasher cleaning products.
Unlike other acids, sodium bisulfate is very stable in its dry form and will not dissolve in water (hygroscopic). When mixed with a liquid, it lowers the pH of the liquid.
It can be used to control the pH of many types of water and is often incorporated in swimming pool products. It is also an additive in a variety of foods, including baked goods and fresh-cut fruits, as it reduces browning caused by sun exposure.
This chemical is corrosive to metals and can damage soft tissue, but it is not carcinogenic in large doses. It is generally considered safe for food use and meets the requirements of the FDA.
sodium hydrogen sulfate, purified is used in metal finishing, cleaning products and to lower the pH of water for effective chlorination. It is also used as a urine acidifier to reduce urinary stones in cats. It is also an ingredient in jewelry making and a component of anti-browning products applied to fresh-cut fruits.

Foam concrete blocks consist of foam which is mixed with cement and sand. These blocks cost less than regular concrete blocks, but they resist cracking. They are also environment-friendly. To get the best performance, quality blocks are required.
Less expensive that traditional concrete blocks
Concrete block is versatile and can be used for foundations, walls, partitions, etc. They are relatively easy to clean, fire resistant and can provide sound insulation. They are an excellent choice for commercial buildings. Concrete blocks may be more costly than wooden, so make sure you understand all the details before selecting the best one for you.
Concrete blocks made from cement are available in many sizes. The most popular sizes of concrete blocks are 4, 6, 8″, and 10. Other sizes are available from some manufacturers. Concrete blocks of any size must adhere to ASTM standards in order for durability and tolerance.
More durable
Researchers are trying to find ways of making foam concrete blocks more resilient. It is important to first characterize the material. The first step is to characterize the material. In past studies foamed concrete was identified primarily as a structural materials with high compressive strength. The concrete has a low dry mass and is easily molded into hollow or solid blocks of concrete with densities between 1800-2400 kg/m3.
Consider the intended application of the concrete block. Because different concrete blocks can have unique properties, they are best suited for different areas. Some block require reinforcement and others can be sound or thermally insulated more effectively. Cost is another important factor to take into account when choosing the type of concrete block.
Resistant against cracking
They are popular for commercial as well as residential constructions. The blocks are lightweight and offer a strong thermal barrier. China’s GB 11968 certified this product. It is a high-quality product with A5.0 strength and B06 densities. The product is very easy to use and provides great value. Below are some suggestions to help keep cracks down.
Concrete blocks are popular for their versatility and use in building structures. They are however not environmentally-friendly. Every year, the cement-making process releases six billion tonnes of CO2. The majority of the CO2 released each year is caused by the conversion of limestone to cement and burning fossil fuels.
In order to meet insulation requirements in many buildings, there are now thicker walls. These requirements can be met by foam concrete blocks. Foam concrete blocks can also be used because they are lightweight and porous. These are an excellent choice for both residential and commercial constructions. They can also be used to reduce cooling costs, and they are much more long-lasting than traditional bricks. They also have mold resistance.
