What is zinc sulfide used for? The most common use of zinc sulfide powder is as a pigment for paints, plastics, and rubber. Lithopone, a mixture of ZnS and barium sulfate (BaSO4), is a widely used pigment for low-gloss paints. ZnS is phosphorescent, which makes it useful for several electronic and decorative applications.
High-purity zinc sulfide powder is an important basic material widely used in high-tech fields such as civil, aerospace, and other high-tech fields.

The applications of Zinc Sulfide are as following:
Luminescent material
Zinc sulfide powder, coupled with a small amount of suitable activator, is currently used in various applications from cathode ray tubes to X-ray screens to emit light in dark products. When silver is used as the activator, the resulting color is bright blue with a maximum of 450 nm. The use of manganese produces an orange-red color of about 590 nm. Copper can glow for a long time and has the familiar dark green glow effect. Copper-doped zinc sulfide ("ZnS + Cu") is also used in electroluminescent panels.
Optical materials
Zinc sulfide powder is also used as an infrared optical material, transmitting from visible light wavelengths to just over 12 microns. It can be used as a flat surface as an optical window or shaped as a lens.
Pigment
Zinc sulfide powder is a common pigment, sometimes called statolith. When combined with barium sulfate, zinc sulfide forms lithopone.
