Zinc Oxide Micro Powder
Zinc oxide Micro Powder is an inorganic compound with the formula is a white powder that is insoluble in water. It is used as an additive in numerous materials and products including cosmetics, food supplements, rubbers, plastics, ceramics, glass, cement, lubricants, paints, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, and first-aid tapes. Although it occurs naturally as the mineral zincite, most zinc oxide is produced synthetically. ZnO is a wide-bandgap semiconductor of the semiconductor group.
The native doping of the semiconductor due to oxygen vacancies or zinc interstitials is n-type. Other favorable properties include good transparency, high electron mobility, wide bandgap, and strong room-temperature luminescence. Those properties are valuable in emerging applications for transparent electrodes in liquid crystal displays, energy-saving or heat-protecting windows, and electronics as thin-film transistors and light-emitting diodes
Physical Properties of Zinc Oxide Micro Powder
Zinc oxide crystallizes in two main forms, hexagonal wurtzite and cubic zincblende. The wurtzite structure is most stable at ambient conditions and thus most common. The zincblende form can be stabilized by growing on substrates with a cubic lattice structure. In both cases, the zinc and oxide centers are tetrahedral, the most characteristic geometry for Zn. It converts to the rocksalt motif at relatively high pressures about 10 GPa. T
he many remarkable medical properties of creams containing ZnO can be explained by its elastic softness, which is characteristic of tetrahedral coordinated binary compounds close to the transition to octahedral structures. Hexagonal and zincblende polymorphs have no inversion symmetry a reflection of a crystal relative to any given point does not transform it into itself. This and other lattice symmetry properties result in piezoelectricity of the hexagonal and zincblende ZnO, and pyroelectricity of hexagonal ZnO.
Mechanical properties of Zinc Oxide Micro Powder
ZnO is a relatively soft material with an approximate hardness of 4.5 on the Mohs scale. Its elastic constants are smaller than those of relevant semiconductors, such as GaN. The high heat capacity and heat conductivity, low thermal expansion, and high melting temperatures are beneficial for ceramics.
The E2 optical phonon exhibits an unusually long lifetime of Among the tetrahedrally bonded semiconductors, it has been stated that has the highest piezoelectric tensor, or at least one comparable to that of GaN and AlN. This property makes it a technologically important material for many piezoelectrical applications, which require a large electromechanical coupling. Therefore ZnO has been in forms of thin-film one of the most studied resonator material for thin-film bulk acoustic resonators.

Ferrochrome Nitride Powder Description:
Ferrochrome nitride is widely used in electric furnace and oxygen converter smelting nitrogen steel. Nitrogen is an element of austenite formation, It is used as a component to add chromium manganese and chromium manganese nickel stainless steel to replace the shortage of nickel.Ferrochrome Nitride Powder Application:
Ferrochrome, or ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy of chromium and iron, generally containing 50 to 70% chromium by weight.
Ferrochrome is produced by electric arc carbothermic reduction of chromite. Most of the global output is produced in and India, which have large domestic chromite resources. Increasing amounts are coming from Russia and China.
Production of steel, especially that of stainless steel with a chromium content of 10 to 20%, is the largest consumer and the main application of ferrochrome.
Ferrochrome production is essentially a carbothermic reduction operation taking place at high temperatures. Chromium ore (an oxide of Cr and Fe) is reduced by coal and coke to form the iron-chromium alloy.
The heat for this reaction can come from several forms, but typically from the electric arc formed between the tips of electrodes at the bottom of the furnace and the furnace hearth.
This arc creates temperatures of about 2,800 °C (5,070 °F). In the process of smelting, huge amounts of electricity are consumed, making production very expensive in countries where power costs are high.
The tapping of the material from the furnace takes place intermittently. When enough smelted ferrochrome has accumulated in the furnace hearth.
The tap hole is drilled open and a stream of molten metal and slag rushes down a trough into a chill or ladle. Ferrochrome solidifies in large castings that are crushed for sale or further processed.
Ferrochrome is generally classified by the amount of carbon and chrome it contains.
The vast majority of FeCr produced is "charge chrome" from South Africa, with high carbon being the second largest segment followed by the smaller sectors of low carbon and intermediate carbon material.

Iron Boride Powder Description
Iron Boride Powder is often used to improve abrasion resistance, corrosion resistance, wear resistance, and oxidation resistance. It is used in oil and gas refinery, chemical extraction, automotive agricultural, stamping, textile extrusion, and injection molding industries. Iron-based coatings recently gained attention for their mechanical, frictional, and corrosion-resistant properties. As compared to the ceramic or cermet type of materials people have used before, iron-based materials are relatively inexpensive, less strategic, and can be produced economically by various thermal methods with ease of fabrication and machining.

Brief Description of WC Tungsten Carbide Powder
Tungsten carbide powder (chemical formula: WC ) is a chemical compound (specifically, a carbide ) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine Gray powder, but it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments, and jewelry. Physical Properties of WC Tungsten Carbide Powder Tungsten carbide has a high melting point at 2,870 °C (5,200 °F), a boiling point of 6,000 °C (10,830 °F) when under a pressure equivalent to 1 standard atmosphere (100 kPa), the thermal conductivity of 110 W·m−1·K−1, and a coefficient of thermal expansion of 5.5 µm·m−1·K−1. Tungsten carbide is extremely hard, ranking about 9 on Mohs scale, and with a Vickers number of around 2600. It has Young’s modulus of approximately 530–700 GPa, a bulk modulus of 630–655 GPa, and a shear modulus of 274 GPa. It has an ultimate tensile strength of 344 MPa, the ultimate compression strength of about 2.7 GPa and a Poisson’s ratio of 0.31. Chemical Properties of WC Tungsten Carbide Powder There are two well-characterized compounds of tungsten and carbon, WC and tungsten semi abide, W2C. Both compounds may be present in coatings and the proportions can depend on the coating method.
