Other name: C.I. Pigment White 5, C.I. 77115, Barium zinc sulfate
EINECS No.: 215-715-5
ZnO: 28-30%
Molecular Formula: ZnS+BaSO4
Physical appearance: white powder, non-toxic, tasteless, odourless, insoluble in water




Lithopone by BaSO4 and ZnS two kinds of components, mixing the two components in the coating is not a separate state. BaSO4 has a diamond crystal structure; ZnS has cubic or hexagonal crystal structure.

Lithopone pigment than zinc sulfide in wide use. The structure is similar to that of ZnS, which contains barium sulfate, and the durability is slightly worse. Poor powdering resistance. The price is low, so it can be partially substituted for tio2.
