Barium sulfate precipitated
Performance: Amorphous white powder. The relative density is 4.50. The temperature of 1580 ° C. Insoluble in water, ethanol and acid. Soluble in concentrated sulfuric acid, easy to agglomerate when dry. Co-heating with carbon to reduce strontium sulfide. In the air, hydrogen sulfide and toxic gases do not change color.
Advantages: "YLFT" precipitated barium sulfate has the advantages of strong chemical inertness, good stability, acid resistance, alkali resistance, moderate hardness, high specific gravity and good whiteness. It can be used as a white filler or as a filler for rubber and paper, which increases its weight and smoothness. Used as filler, brightener and weighting agent in rubber, plastic, paper, paint, ink, paint and other industries. The use of glass articles as clarifying agents can act to defoam and increase gloss. It can be used as a protective wall material for radiation protection. Also used in ceramics, enamel, spices and pigments. It is also a raw material for the manufacture of other barium salts.
Application: Widely used in various coatings, plastics, rubber, paints, inks, insulating tapes, ceramics, batteries, enamel and other industries. Can be used in acid resistant rubber products and general products. It can also be used as a surface coating agent, a sizing agent, a weighting agent, and the like.
