Zinc sulphide ZnS mixed with barium sulphate is used as a white pigment known as lithopone. ZnS is also used as a detector of alpha-rays, which render it luminescent.  ZnS and the selenide ZnSe are used in infrared optics.  Zinc salts have various applications: zinc chloride in the textile industry, and as a scaling flux in galvanizing; zinc sulphate in agriculture and animal feed; zinc phosphate to passivate steels, etc. Organic salts of zinc are used in paints, and zinc stearate is used in the preparation of plastics as well as in powder metallurgy.

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 Lithopone has mostly been replaced by titanium dioxide which is more durable, but it is much cheaper.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