Description
Natural ore of barium sulfate: (BaSO4). It has rhombic crystal structure; refractive index: 1,64; specific gravity: 4,25-4,50; oil absorption: ~10 g/100 g baryte. The micronised filler, obtained from grinding of the natural ore, is a widely used matting agent for cost reduction purposes because of its low oil absorption value and high density especially when price per weight is important.
