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 primarily in chemical manufacturing and paints. 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 wear resistance and high refractive Index, have a high hiding power when covered with wax paper, metal plates, or equipment.
Zinc sulfuride is easy and simple to disperse. It is commonly used in thermosetting, thermoplastics and reinforced fiberglass as well flame retardants, flame-resistantants, artificial rubber, and dispersants.
2. Ceramics
Ceramics use zinc sulfide because of its excellent sintering characteristics. Research has shown that the monodisperse zinc sulfide particles have a higher sintering ability than the agglomerated, and that the size of the particles affects the performance.
3. Photoelectric
Zinc sulfuride is a wide bandgap semiconductor that can also be used as a 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 large screen displays such as computer terminals and radars.
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. Infrared performance
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.
