Nature Insoluble Barium Sulphate Powder XM-BA45 has the luster of glass, non-magnetic and non-toxic. And materials with environmental protection functions, so they are widely used in various coatings, medium and high-grade inks, rubber, papermaking, ceramics, cosmetics and other fields. Refined barium sulfate is also used in medium and high-grade paints, engineering plastics (household appliance shells, building materials plastics), high-grade insulating rubber, rubber products, cathode expansion rods of batteries, and glaze materials of ceramics and enamel.
