Zinc sulfide is an inorganic compound with a chemical formula of ZnS. Its appearance is white to off-white or light yellow powder. Zinc sulfide is stable in dry air, and when left in humid air for a long time or contains moisture, it will gradually oxidize to zinc sulfate.

Zinc Sulfide Powder Properties

Zinc sulfide powder is soluble in dilute inorganic acid, soluble in alkali, but insoluble in water. Zinc sulfide powder is irritating.

Zinc sulfide is generally obtained by the action of hydrogen sulfide and zinc salt solution. If a small amount of Cu, Mn, Ag is added as an activator in the crystalline ZnS, it can emit different colors of fluorescence after being illuminated.

Zinc sulfide has excellent fluorescence effect and electroluminescence function. Nano-zinc sulfide has a unique photoelectric effect. It has many excellent properties in the fields of electricity, magnetism, optics, mechanics and catalysis.


Zinc Sulfide Powder Applications

1. Chemical
Zinc sulfide is mainly used in paints and plastics in chemical production. Because of its white opacity and insoluble in water, organic solvents, weak acids and weak bases, it has become an important pigment in paints. Zinc sulfide is easy to disperse and not agglomerate. It is neutral white and has good optical properties. It is often used as a component of thermosetting plastics, thermoplastics, reinforced fiber glass, flame retardants, artificial rubber and dispersants.

2. Ceramics
Because zinc sulfide has good sintering properties, it is applied to ceramics. Studies have shown that the sintering performance of monodisperse zinc sulfide powder is higher than that of agglomerate zinc sulfide, and the sintering performance is enhanced with the decrease of particle size.

3. Optoelectronics
Zinc sulfide is a wide band gap semiconductor and a potential photonic material. Zinc sulfide is used for digital, text, symbol and automatic simulation display, computer terminal and radar display, large screen display, in military, transportation, post and telecommunications, etc.

4. Photocatalysis
Because nano-zinc sulfide is a photonic material, it can generate photon holes, and the energy level change and the widening of the energy gap brought about by the quantum size effect enhance its redox ability. It is an excellent photocatalytic semiconductor.

5. Infrared performance
Zinc sulfide is an infrared optical material. It has high infrared transmittance and excellent optical, mechanical and thermal comprehensive performance in the 3-5p.m and 8-12ym bands. It is the best dual-band infrared observation window for aircraft and Hood material. When using this property as a special absorbing material for pigment doping, a single particle with a larger particle size is required, and it can be modified by a metal nano-layer wrapped on the surface of zinc sulfide.
