Although ZnS is usually black due to impurities, the pure material is white and is used as a pigment. Zinc sulphide becomes a luminescent material when activated with a suitable activator. This property of ZnS has several applications. For example, it is used as a phosphor in cathode ray tubes.
Application of Zinc Sulfide Pigment
The most common use of zinc sulfide powder is as a pigment for paints, plastics, and rubber. It is 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 whiteness：S-10 is a blue-phase white pigment, with brightening effect, can improve the efficiency of phosphors.
Thermal conductivity: S-10 has good thermal conductivity, with a thermal conductivity of 27W/(m·k), higher than that of alumina.
Low UVA absorption rate
It has a low UVA absorption rate and can be used in UV-curable white paints to improve efficiency.
Liquidity
S-10’s particle size distribution is narrow, the particles are nearly spherical. Even in a high solid content system, it has relatively good liquidity.
High purity
Zinc sulfide products have high purity, do not contain other harmful trace elements, ensure the stability of products.

Zinc Sulfide Pigment and Method of Making Same
A method of manufacturing an improved zinc sulfide pigment, comprising: In an aqueous reaction zone at a temperature at or near the boiling temperature and a substantially constant ph, reacting zinc sulfate and a thiosulfate selected from the group consisting of ammonium thiosulfate, potassium thiosulfate, sodium thiosulfate, and the like, precipitating therefrom crude zinc sulfide particles generally cubic, soft, and fully formed during said precipitating,separating the resulting crude pigment particles precipitate from the mother liquor.
Passing the resulting washed particles into a pebble mill in circuit with a classifier and grinding same therein by trituration while turning said pebble mill at a relatively slow speed and rolling the pebbles therein, splitting off laminae from the surface of said particles and producing a plurality of thinner particles of substantially the same planar dimension, such being lamellar zinc sulfide pigment particles having a thickness less than the planar dimensions, removing the resulting lamellar zinc sulfide pig- 10 ment particles from said mill and passing same into a drying and calcining zone, and therein drying and calcining same, cooling the resulting calcined pigment particles, and pulverizing in a dry condition the cooled pigments to produce a zinc sulfide pigment product.
