    Barium sulfate (barium sulfate) is a barium sulfate salt. Chemical formula - BaSO4

    Analytical chemistry

    In analytical chemistry, barium sulfate is used as a good gravimetric form for the determination of sulfate ions and barium ions in gravimetric analysis.

    Radiopaque substance

    It is often used in X-ray studies of the gastrointestinal tract as a radiocontrast substance, since heavy barium atoms absorb X-rays well. Although all soluble barium salts are poisonous, barium sulfate is practically insoluble in water (and in the hydrochloric acid solution found in gastric juice), so it is non-toxic. For X-ray examination of the digestive organs, the patient takes orally a suspension of barium sulfate ("barium porridge") with a barium content of 58.7%.

    Pigment-filler

    Sulfate barium is one of the constituent mixtures used as white pigments:

    1. A mixture of barium sulfate with zinc sulfide, obtained by the interaction of solutions of barium sulfide and zinc sulfate - lithopone.
    2. Fine crystalline barium sulfate, obtained by the interaction of precipitation of sodium sulfate from a solution of barium sulfide - Blanc fixe.

    It is used as a glue paint, since it is insoluble in organic solvents. This whitewash is cheaper than lead, in contrast, they are non-toxic and do not darken from hydrogen sulphide.

    Other uses

    Barium sulphate is used for various industrial purposes:

    • As a filler for photographic and writing paper, for linoleum and for some varnish-and-paint materials. See, for example, baritage.
    • As a white filler for plastics, and as a component of drilling fluids to increase their density.
    • In photometry: for painting photometric balls
    • In the electrochemical industry in the manufacture of lead-acid batteries as an expander of the active mass of the negative electrode.
    • In the production of glass etching paste.
