Properties: Lithopone is a white pigment composed of a mixture of barium sulfate(28-30%)and zinc sulfate(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 Lithopone has mostly been replaced by titanium dioxide which is more durable, but it is much cheaper .It is used as a base for lake pigment and used as a inert pigment for paint, ink and cosmetics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 application in plastic industry .It is used as a filler in paper, leather, and linoleum.
