Germanium dioxide, the molecular formula GeO 2, and the electronic formula is the same as carbon dioxide. Dry germanium oxide does not irritate the skin, but it does irritate the conjunctiva. It is white powder or colourless crystals. There are two kinds of hexagonal systems (low temperature stability) slightly soluble in water and insoluble cubic systems. The transition temperature is 1033 C.

Thorium oxide, molecular formula ThO 2, is radioactive. It is used for making high temperature ceramics, atomic fuel, incandescent lamp, cathode of electron tube, electrode for arc melting, optical glass, refractory material and catalyst.
Titanium nitride is a new kind of multifunctional cermet material. It has high melting point, high hardness and low friction coefficient. It is a good conductor of heat and electricity.
Chromium powder, also known as basic chromium sulfate, molecular formula Cr (OH) nSO40.5 (3-n), relative molecular weight 165.07, salinity 33%.
Manganese nitride is an additive in iron-making. Adding a certain amount of manganese nitride in steel smelting can improve the strength and mechanical properties of steel. Therefore, manganese nitride is an indispensable alloying agent in the production of special alloy steel and stainless steel. But manganese nitride will be affected by some factors in production.
Iron nitride is an inorganic compound, gray powder, insoluble in water, and may release ammonia after heating or exposure to humid environment.The appearance of iron nitrides is basically grey powder. Iron has four kinds of nitrides: Fe2N, Fe3N1 + x, Fe4N and Fe16N2. They are crystalline metallic solids.
Chromium nitride is deposited by cathodic arc plasma. Cathodic arc plasma deposition is a relatively new thin film deposition technology, which is similar to ion plating in many aspects. Advantages: high ionization rate in the emitted particle stream, and these ionized ions have high kinetic energy (40-100eV). Many advantages of ion beam deposition, such as increasing adhesion force, increasing density of states, and high reaction rate to the formation of compound films, are reflected in cathodic arc plasma deposition.
Nickel-coated graphite powder is a composite powder with graphite particles as its core and nickel metal as its outer coating. With good lubrication and corrosion resistance, nickel was evenly deposited on the surface of graphite particles from nickel sulfate ammonia complex solution by wet hydrogen reduction It was used to manufacture high temperature self-lubricating bearing materials, low friction materials, porous nickel strips, etc. Grindable sealing coatings can also be obtained by thermal spraying.
Metal powders are prepared by electrolysis atomization and ball milling. All of them are physical changes, so electrolytic manganese is manganese powder.Electrolytic manganese metal is the main material for manufacturing manganese trioxide. In addition, because of its high purity and low impurity, it is an important alloy element for producing stainless steel, high strength low alloy steel, Al-Mn alloy, copper-manganese alloy, etc.
Nickel powder is also divided into carbonyl nickel powder, uniform color, no caking and reunion, no visible inclusions. It is mainly used for coatings and plastics as conductive pigments to shield electromagnetic interference and radio frequency interference, for various high gloss decorative paints and plastics, instead of aluminium powder as anticorrosive paint in water system, etc.
