High Whiteness and Purity Precipitated Barium Sulphate

High whiteness and purity precipitated barium sulphate  precipitated barium sulfate is produced by advanced chemical precipitation method. It has good phisycal properties: low impurity, excellent fineness, white powder or paste, non-toxic, insoluble in water, soluble in fuming sulphuric acid, stable chemical property. Can absorb x-ray, and endow the materials with high density and surface finish, therefore widely used in paints, printing ink, coatings, plastics, rubber, chips, friction plate, ceramics, glass, electronics, cosmetics, pharmacy and food etc.   item   barium sulphate precipitated   barium sulphate superfine baso4  % 98.0 min  93-98 min 105 °c volatiles  % 0.3 max   0.50 max water solubles  % 0.3 max.  0.5 max moisture  %  0.15 max  0.2 max ph 6.5-8.0   6.5-8.0 oil  absorption  g/100g 10-30    10-30 whiteness 96 min   90-96 min specific gravity g/cm3 4.0-4.5.
