Properties: 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.
Applications: 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 Lithopone has mostly been replaced by titanium dioxide which is more durable, but it is much cheaper.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.
