What is barite? What performance do you need to measure?
Barite is a mineral containing calcium, sulfur and oxygen with the chemical formula CaSO4. It usually exists in colorless or white crystalline form and is one of the sulfate minerals. Barite is widely used in industry, including in the manufacture of gypsum boards, gypsum molds, sulfate fertilizers, cement additives, etc.
