| physicochemical properties | White powder, a mixture of zinc sulfide and barium sulfate. White crystalline powder. It is a mixture of zinc sulfide and barium sulfate. The more zinc sulfide it contains, the stronger the hiding power and the higher the quality. Density 4.136~ 4.34 g/cm3, insoluble in water. It is easy to decompose in case of acid to produce hydrogen sulfide gas, but it does not work in case of hydrogen sulfide and alkali solution. It turns light gray when irradiated by ultraviolet rays in sunlight for 6~ 7 hours, and still restores its primary color in a dark place. It is easy to oxidize in the air, and it agglomerates and deteriorates after being damp. Its whiteness and hiding power are stronger than zinc oxide, and its refractive index and opacity exceed zinc oxide and lead oxide, but it is inferior to titanium dioxide. |
| purpose | For coloring of paints, inks, rubber, etc Inorganic white pigment, widely used in polyolefins, vinyl resins, ABS resins, polystyrene, polycarbonate, nylon and polyoxymethylene and other plastics as well as white pigments for paints and inks. Less effective in polyurethane and amino resins, less applicable in fluoroplastics. Also used in the coloring of rubber products, papermaking, lacquered cloth, canvas, leather, watercolor pigments, paper, enamel, etc. Used as an adhesive in the production of electric beads. |
