Appearance - Pure white piece crystals
Properties and Features - Zinc sulfide (or zinc sulphide) is a inorganic compound with the formula ZnS. ZnS is the main form of zinc in nature, where it mainly occurs as the mineral sphalerite. Although the mineral is black owing to impurities, the pure material is white and is in fact used widely as a pigment.

Application Field - Optical material,Zinc sulfide is also used as an infrared optical material, transmitting from visible wavelengths to over 12 micrometres. It can be used planar as an optical window or shaped into a lens. It is made as microcrystalline sheets by the synthesis from hydrogen sulfide gas and zinc vapour and sold as FLIR grade ZnS a pale milky yellow visibly opaque form. This material when hot isostatically pressed can be converted to a water-clear form known as Cleartran.

Pigment, Zinc sulfide is a common pigment. When compounded with barium sulfate, zinc sulfide forms lithopone.

Semiconductor, Both sphalerite and wurtzite are intrinsic, wide-bandgap semiconductors. It is a prototypical semiconductors and adopts structures related to many other semiconductors such as gallium arsenide. The cubic form has a band gap of 3.54 eV at 300 K whereas the hexagonal form has a band gap of 3.91 eV. It can be doped as both n-type semiconductor and p-type semiconductor.
