Industrial preparation method and application of copper oxide CuO powder

圖片
  Overview of copper oxide CuO powder Copper oxide  is an inorganic substance with the chemical formula CuO, which is a black oxide of copper, slightly amphiphilic and slightly hygroscopic. It is insoluble in water and ethanol, and easily soluble in acid. It is stable to heat and decomposes oxygen at high temperature. Copper oxide is mainly used to make rayon, ceramics, glazes and enamels, batteries, petroleum desulfurizers, pesticides, and also for hydrogen production, catalysts, green glass, etc. Industrial production method of copper oxide CuO powder 1. Copper powder oxidation method Using copper ash and copper slag as raw materials, it is roasted and heated with coal gas for preliminary oxidation to remove moisture and organic impurities in the raw materials. The generated primary oxide is naturally cooled, and after pulverization, it undergoes secondary oxidation to obtain crude copper oxide. The crude copper oxide is added to the reactor pre-installed with 1:1 sulfuric a...

The properties and applications of titanium nitride TiN

  Titanium nitride TiN overview Titanium nitride  is a compound with a molecular formula of TiN and a molecular weight of 61.88. TiN powder is generally yellowish brown, ultrafine TiN powder is black, and TiN crystals are golden yellow. TiN has a melting point of 2950°C, a Mohs hardness of 8-9, and good thermal shock resistance. The melting point of TiN is higher than that of most transition metal nitrides, but the density is lower than that of most metal nitrides. Titanium Nitride (TiN) is a very hard ceramic material, usually used as a coating for titanium alloys, steel, carbides and aluminum parts to improve the surface properties of the substrate. The Vickers hardness of TiN is 1800-2100, the modulus of elasticity is 251 GPa, the coefficient of thermal expansion is 9.35×10-6 K-1, and the superconducting transition temperature is 5.6K. The properties of titanium nitride TiN There are two kinds of titanium nitride (Ti2N2) and titanium tetranitride (Ti3N4). Titanium dinitride...

It decomposes in high humidity or humid air, dissolves in acid, and releases ammonia and alkali. Production method of lanthanum nitride LaN powder The dehydrated chloride is dissolved in methanol, and electrolysis is carried out with a graphite anode (d=12mm) and a mercury cathode. The electrolysis vessel is equipped with multiple ground glass joints for inserting the graphite anode, agitator, and N2 gas conduit. The inlet and outlet, t...

CoCrMo alloys are known for their high wear resistance and corrosion resistance

  Overview of  3D metal printing CoCrMo powder CoCrMo alloy  (cobalt-chromium molybdenum) is one of the cobalt-base alloys, is also commonly known as a Stellite alloy, is a kind of wear and corrosion resistance of the cobalt-base alloy.CoCrMo alloys are particularly susceptible to work hardening and therefore cannot be manufactured in the same way as other metals, requiring vacuum precision casting instead. Controlling the mold temperature can control the grain size of the casting. The formation of coarse grains at higher temperatures will reduce the strength, but it will also precipitate large and far apart carbides and reduce the brittleness of the material.CoCrMo alloys are known for their high wear resistance and corrosion resistance. Because of their good biocompatibility, they are widely used in surgical prostheses. The microstructure and properties of CoCrMo alloys, such as wear-resistance and hardness, are mainly determined by the carbon content and the heat treat...

Potassium oleate (CAS 143-18-0) is a potassium catalyst

圖片
  Overview of Potassium Oleate Potassium oleate  is an organic compound called long-chain fatty acid. These are fatty acids with 13 to 21 carbon atoms in the aliphatic tail. Potassium oleate is a weakly acidic compound (based on its pKa). Potassium oleate is a kind of potassium catalyst, mainly used for the reaction of polyisohydrourethane in polyurethane foam. It can also be used as rubber emulsifier, foaming agent, release agent, detergent, lubricant, fiber Softener and surfactant. Potassium oleate is a natural component of vegetable oils (such as sunflower oil). It is used to make soap and make vegetable glycerin soap. In its pure state, it may be irritating, but in soap making, the dosage can be reduced and it is approved as food safe when used as a binding ingredient. Potassium oleate is a product with high wetting, non-stick, foaming ability, and can be used in industrial fields, such as the manufacture of Marseille soap. It is a surface active agent whose main function ...
