Ce este baritul? What performance needs to be tested?
Baritul este un mineral care conține calciu, sulf și oxigen cu formula chimică CaSO4. It usually exists in a colorless or white crystalline form and is one of the sulfate minerals. Barite has a wide range of industrial applications, including its use in the manufacture of plasterboard, plaster molds, sulfate fertilizers, cement additives, etc.
