Cobalt oxide (Co203) is an expensive cobalt oxide with a theoretical cobalt content of 71.06%, an oxygen content of 28.94%, and a density of 6.079/cm3. It is a black amorphous powder that generates cobalt oxide (Co304) after heating. Cobalt oxide is an unstable compound and cannot be freed. The cobalt oxide commonly referred to actually still contains a certain amount of cobalt tetraoxide. Co203 is only stable in a hydrated state. This hydrate will dehydrate and transform into the intermediate oxide cobalt tetraoxide (Co304) at 265�°C. Cobalt oxide is reduced to cobalt tetraoxide (Co304) by H2 at 125�°C, reduced to CoO at 200�°C, and reduced to cobalt metal at 250�°C. Cobalt oxide is insoluble in water. After dissolving in water, it decomposes into hydrates when it encounters water. It is insoluble in water, but soluble in acid and forms corresponding salts.
Nickel is a hard, ductile and ferromagnetic metal that is highly polished and resistant to corrosion. Nickel is a ferrophilic element. The core is mainly composed of iron and nickel elements. In the crust, iron-mafic rocks contain more nickel than silico-alumina rocks. For example, peridotite contains 1,000 times more nickel than granite, and gabbro contains 80 times more nickel than granite. On October 27, 2017, the World Health Organization's International Agency for Research on Cancer released the preliminary list of carcinogens for reference. Nickel compounds are in the list of carcinogens, metal cobalt, metal nickel and 66-67% nickel, 13-16% nickel. Chromium and 7% iron alloy powders for implantation of foreign bodies in vivo, nickel metal and nickel alloys are on the list of Class 2B carcinogens. Niclkel powder is mainly used in atomic energy industry, conductive materials, battery electrode materials, chemical catalysts, hard surface spray welding, special welding rods, porous filter materials, magnetic materials, contact materials, Diamond tools, automobile manufacturing, cemented carbide, high-temperature high-strength alloys and other powder metallurgy fields.

Powder metallurgy is a manufacturing process where various powder metals such as stainless steel, brass, copper, iron and bronze are compressed and then sintered (heated) to increase adhesion between particles. Material blending allows for a certain amount of customization of material properties to produce desired characteristics suitable for a particular application. The part is formed by compressing the powder metal, or blended metal powders, in accurately formed dies and punches in special types of hydraulic presses. The compressed pieces are then sintered in an atmosphere controlled furnace at high temperatures, causing the metal powder particles to be metallurgically bonded together. This remarkably greenand environmentally friendly process uses 99% of the material thats in the mold, producing harmless bi-products of nitrogen and hydrogen. Optional operations include sizing or coining. Supplementary heat treatments may also be employed to increase material strength. Other optional finishing steps include milling & machining, grinding, drilling & tapping, reaming & other hole sizing, plating, and cu, plastic or oil impregnating. The result is high density parts comparable to wrought products of the sam e composition and surpassing plastic and die cast material properties. Lower density will, of course, result in lower physical properties; however, these parts can be used in filter or air flow applications. -
