White crystalline powder. A mixture of barium sulfate and zinc sulfide, zinc sulfide containing more hiding the stronger, the quality is also higher. insoluble in water. Yi met acid decomposition of hydrogen sulfide gas, hydrogen sulfide and alkali solution does not work the case. By ultraviolet sunlight irradiation 6 ~ 7h become light gray, dark place still restore its original color. Easily oxidized in air, damp curdle.
Physical properties: white powder, is a mixture of barium sulfate and zinc sulfide. Its whiteness, strong hiding power than zinc oxide, the refractive index and opaque force of more than zinc oxide and lead oxide, titanium dioxide, but inferior
use
Lithopone good heat resistance, weather resistance can be improved, anti-algae, as well as reduce the cost of having excellent whiteness shielding force. Easily oxidized in air, damp caking. Whiteness, strong hiding power. Zinc sulfide containing more, hiding the more strong, and the quality is also higher. Barium sulfate and zinc sulfide precipitation from the reaction solution obtained, was filtered, dried and pulverized, and then calcined to red hot, poured into water quench derived. Hiding power inferior to titanium dioxide, intolerance concentrated sulfuric acid. Applications: Widely used as the polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon and POM plastics and coatings, paints, inks, plastics, rubber, linoleum, leather, paper, enamel, etc. .

Lithopone is a white, inorganic pigment composed of a mixture of barium sulfate (BaSO4) and zinc sulfide (ZnS). It is widely used in the production of paints, coatings, and printing inks due to its exceptional opacity and brightness. Lithopone enhances the covering power of these products, making it especially valuable in applications where whiteness and opacity are critical, such as in the manufacturing of high-quality paints and paper. It also contributes to corrosion resistance and durability in coatings. Despite its historical use, its production has declined in recent years due to environmental concerns related to the presence of barium compounds, with many industries opting for alternative white pigments like titanium dioxide. Nonetheless, lithopone's unique properties continue to make it relevant in certain niche applications within the paint and coatings industry.

Lithopone B301/B311(30%) Lithopone B311(30%) is a kind of lithopone whose hiding power is better than that of zinc oxide and worse than that of titanium dioxide.It has good heat-resisitance and is insoluble in water. White powder, is a mixture of zinc sulfide and barium sulfate. Have high whiteness and good covering power. It is called Inorganic white pigment. Widely used as white pigment of plastics such as polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon and polyoxymethylene (POM), also for paint,ink ,grinding wheel and plaster. It is use to colourate for rubber products , linoleum, leather, paper, enamel.
