Insoluble in acids, alkalis, and solvents! Widely used in paints, plastics, and other industrial raw materials and inorganic fillers.
"Barium sulfate" generally refers to the powdered form of the mineral barite, commonly known as natural barite, which is the ground product of barium sulfate (barite powder) and precipitated barium sulfate produced through chemical reactions. Due to its high specific gravity and its physical and chemical stability, it is widely used as an industrial raw material and inorganic filler in paints, plastics, and more. Precipitated barium sulfate can have its particle size controlled depending on the conditions during synthesis, allowing for the production of extremely fine barium sulfate. 【Features】 ■ High specific gravity (4.2–4.5) ■ Heat resistance (melting point 1580°C) ■ Chemical resistance (stable in acids and alkalis) ■ Radiation shielding *For more details, please refer to the PDF document or feel free to contact us.
