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.

What is barite? What performance do you need to measure?

Among them, the particle size distribution and specific surface area are usually measured by liquid displacement method and specific surface area meter method. Color can be detected by spectrophotometry and colorimeter; The purity is often determined by X-ray fluorescence spectrometry and ICP-MS. Density can be detected by densitometer method; Fluorescence performance can be measured by fluorescence spectroscopy and UV absorption spectroscopy.
