China barite powder

China barite powder Barite, chemical formula BaSO4, it also contains Sr and Ca. Stable chemical performance, hardly soluble in water and acid, non-toxic and nonmagnetic, can absorb X-ray and γ-ray. The fine barite powder is widely used in glass-making industry, as filler for paper,  paint,coating and so on.   1.Main Property of barite powder

Chemical formula	Chemical composition/%	Density(g/cm3)	Mohs hardness	Crystal system	Shape	Color
BaSO4	BaO65.7;SO334.3	4.5	2.5 ~3.5	rhombic	tabular column	white or grey-white

Application:oil, paint, chemical industry, rubber, plastic, friction material, glass additives and other industrial departments. 2.Index of barite powder
