The molecular formula of cobalt is Co. Cobalt powder is a gray irregular powder, soluble in acid, magnetic, and easy to oxidize in humid air. As a binder in powder metallurgy, cobalt can ensure the toughness of cemented carbide. Cobalt is also an important part of permanent magnetic alloys, and its performance determines the bonding performance, strength and toughness of super-hard alloy materials, which is very important to the performance of super-hard alloy materials. Cobalt powder is widely used in aviation, aerospace, electrical appliances, machinery manufacturing, chemical and ceramic industries. In the chemical industry, in addition to high-temperature alloys and anti-corrosion alloys, cobalt is also used in colored glass, pigments, enamels, catalysts, and desiccants.
