Barium sulfate’s specifications usual is the BaSO4 in friction material industry which content is 95-98% . Barium sulfate is the chemical synthesis products, which made with soluble barium salt and sulfuric acid after repeated
decomposition reaction , then it doesn&＃39;t contain silica mineral impurities, is frequently used to product high friction brake noise,
