High Pure Product 98.5% Calcium Metal Lump For Steelmaking Deoxidizer
Calcium is a chemical element with a symbol of Ca and an atomic number of 20. As an alkaline earth metal, calcium is very active will form a black coating of nitride and oxide when exposed to the air.
Calcium metal or metallic calcium is a silver-white metal. It is mainly used as a deoxidizing, decarburizing, and desulfurizing agent in alloy steel and special steel production. It is also used as a reducing agent in high-purity rare earth metal processes.
Metallic calcium is produced primarily through two methods: electrolysis of molten calcium chloride, which can achieve purities above 98.5% and up to 99.5% after further processing; and the aluminothermic (or thermite) process, which typically achieves purities around 97% with some impurities like magnesium and aluminum.

Application
Metallic calcium has a wide range of applications due to its excellent properties. Here are some of the main applications of metallic calcium:
- Alloy Preparation: Metallic calcium is often used to prepare alloys with other metals such as aluminum, magnesium, and iron. These alloys exhibit special properties like lightweight, heat resistance, and corrosion resistance, and are widely used in aerospace, automotive, and other industries.
- Medicine: Metallic calcium plays an important role in bone development and bone health. It can be used to treat osteoporosis and fractures, and can also be used to prepare medicinal calcium compounds such as calcium tablets and calcium supplements.
