Ano ang barite? What performance needs to be tested?
Barite ay isang mineral na naglalaman ng kaltsyum, sulfur at oxygen sa chemical formula na 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, atbp.
