Properties: With common properties 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.
