Lithopone is a white pigment, zinc sulfide and barium sulfate mixture.
Zinc sulfate and barium sulfide from the solution derived from the reaction of precipitation, filtration, drying and grinding, then calcined very badly burned red hot, pour into the water quench derived. Opacity secondary to titanium dioxide. No acid. Now some lithopone conducted with surfactant surface.
Lithopone also known as Zinc barium white, non-toxic white powder, insoluble in water, with acid to release hydrogen sulfide decomposition, and hydrogen sulfide and alkali does not work. It is a good heat resistance, weather resistance can be improved, anti-algae, lower costs, and its excellent shielding power whiteness.
Performance
Lithopone pigment widely used than the zinc sulfide. ZnS in structure and composition similar to composition containing barium sulfate, durability little worse. Poor anti-powdering. Cheap, so you can use some alternative to titanium dioxide.
