O que é barita? What performance do you need to measure?
A barita é um mineral que contém cálcio, enxofre e oxigênio com a fórmula química 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..
