Lithopone is a white pigment composed of a mixture of barium sulfate (28 - 30%) and zinc sulfide (68 - 70%) with trace amounts of zinc oxide. It is produced by precipitation through filtering, heating and quenching works. Lithopone has mostly been replaced by titanium dioxide which is more durable, but it is much cheaper. It is used as a base for lake pigment and used as a inert pigment for paint, ink and cosmetics as well as in a large range of applications in plastic industry. It is used as a filler in paper, leather, and linoleum.

Lithopone whose hidina power is better than that of zinc oxide and worse than that of titanium dioxide．It has good heat-resisitance and is insoluble in water．It does not react with sulfureted hydrogen and bases If will decompose and produce sulfureted hydrogen consequently when comes across acids Its color will change after solarization for a long time but can return to its originaI color in dark place．

Brilliant white pigment used in paints, inks, leather, paper, linoleum, and face powder. Lithopone was developed in the 1870s as a substitute or supplement for lead carbonate (white lead), to overcome its drawbacks of toxicity, poor weathering, and darkening in atmospheres that contain sulfur compounds. Lithopone is an insoluble mixture of barium sulfate and zinc sulfide that precipitates upon.
