Lithopone

Lithopone is a mixture of zinc sulfide and barium sulfate. White crystalline powder. Density 4.136 ~ 4.34g /cm3, insoluble in water. In the case of acid decomposition is easy to produce hydrogen sulfide gas, hydrogen sulfide and alkali solution does not work. The more zinc sulfide it contains, the stronger its covering power and the higher its quality.
