White powder, is a mixture of zinc sulfide and barium sulfate. White crystalline powder. For a mixture of zinc sulfide and barium sulfate, zinc sulfide, the more the stronger the covering power, the higher the quality also. 4.136 ~ 4.34 g/cm3 density, insoluble in water. In the acid to produce hydrogen sulfide gas, hydrogen sulfide and alkali solution doesn't work. By the ultraviolet ray in sunlight 6 ~ 7 h into light gray, was back in the dark color. After the easy oxidation in air, and be affected with damp be affected with damp agglomerate metamorphism. Its whiteness, strong hiding power than zinc oxide, refractive index and opaque force than zinc oxide and lead oxide, but inferior to the titanium dioxide
Lithopone pigment widely used than zinc sulfide. Structurally similar to the composition of zinc sulfide, barium sulfate ingredients, durability is a bit poor. Poor resistance to pulverization. Cheaper price, thus can be used to partly replace titanium dioxide.
As a result of the titanium dioxide high dielectric constant, so it has excellent electrical performance. Mi9k_3 in some physical properties of titanium dioxide, want to consider the crystallization direction of titanium dioxide crystals. Sharp titanium type titanium dioxide dielectric constant is low, only 48.
