Uses: Lithopone is a white pigment composed of a mixture of barium sulfate (68 - 70 %) and zinc sulfide (28 - 30%) 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   Lithopone  has mostly been replaced by titanium dioxide which is more durable, but it is  much cheaper.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.
