Apa itu barit? Kinerja apa yang perlu Anda ukur?
Barit merupakan mineral yang mengandung kalsium, belerang dan oksigen dengan rumus kimia 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, dll..
