good quality and best price precipitated barium sulfate BASO4

barium sulphate

Property: With common propertied of the ordinary BaSO4, they have finer powder appearance. The primary particle has a lesser average diameter and is distributed narrower scope The particle, after surface treatment, has greatly improved the flow, the dispersion of powder and the powder's compatibility with applied surface.

Product appearance: White powder.
