Zinc sulfide
This inorganic compound has a chemical composition of ZnS. It’s a white powder or slightly yellowish-colored powder that turns darker when exposed to sunlight. Zinc sulfuride is stable in dry conditions, but slowly oxidizes to zinc oxide if left in humid environments for too long or contains moisture.
Zinc Sulfide Powder Application
Zinc sulfide’s excellent properties make it a popular choice in many areas.
1. Chemical
Zinc sulfuride is used mainly in paints, plastics, and chemical production. Zinc sulfide is an important pigment in paints because of its white opaqueness and insolubility to water, organic solvents as well as weak acids and bases. Zinc sulfide pigments, due to their high refractive and wear resistance, have a high hiding power when coated on equipment, wax papers, or metal plates.
Zinc sulfuride is easy and simple to disperse. It is commonly used as a component in thermosetting plastics and thermoplastics, reinforced glass, flame retardants, artificial resin, dispersants, and thermosetting plastics.
2. Ceramics
Ceramics use zinc sulfide because of its good sintering characteristics. Research has shown that the monodisperse zinc sulfide particles have a better sintering result than the agglomerated. The particle size also increases.
3. Photoelectric
Zinc sulfuride is a broad-bandgap semiconductor and potential photonic material. You can achieve visible emission in different wavelength bands by introducing different dopants to the nano-zinc.sulfide matrix. Zinc sulfide has many uses, including numbers, characters and symbols. It is also used in computer terminals and radar displays.
4. Photocatalysis
Because nano-zinc sulfuride is a type of photonic material it can generate photonic hole. Quantum size effect increases the redox potential, which makes it an excellent photocatalytic silicon.
5. Performance of infrared
Zinc sulfuride is an infrared optic material that has high infrared transmittance, excellent optical, mechanical, and thermal comprehensive properties. It is the ideal dual-band, infrared observation window or hood material to use for aircraft. This property is used to make a special absorbing substance doped in pigments. It requires single particles with larger sizes, which can be modified using a metal nanolayer on the surface zinc sulfide.
