What is it? Zinc Sulfide ? Zin sulfide can be described as an organic compound with a chemical composition of ZnS. This is a white, slightly yellow powder which becomes darker when exposed sunlight. It is stable when dry, but will slowly oxidize to zinc sulfate in humid conditions.
Zinc Sulfide: The key features
1. Physical Properties
Powder that is white to slightly yellow. When heated with H2S gas, it turns into crystals. The a variant, a colorless hexagonal crystal, has a density of 3.98g/cm3 with a melting point at 1700degC. It can also exist in sphalerite. Insoluble in water; soluble in acids. You can see the sun’s color darken.
2. Chemical Properties
If it is left in humid air for too long, it will convert to zinc sulfate. It is generally formed from the interaction of hydrogen sulfide with zinc salt solution. When the crystal ZnS is illuminated with a small amount Cu and Mn, it can produce different colors of fluorescence. To prepare phosphors, coatings or paints, as well as filling rubber and plastics.

Zinc Sulfide: What are the applications?
1. Zinc sulfuride (ZnS), is widely used to make infrared fairings, windows, and optical components. It is highly pure, insoluble in water and has a moderate density. Zinc sulfuride (ZnS), which has excellent refractive index uniformity. It has excellent image transmission performance within the 8-12mm range. Some absorb after 10um. Mid-infrared bands have a higher transmittance and more scattering and absorption. Zinc sulfuride (ZnSe) is strong in harsh environments, has high hardness, and twice as strong as zinc selenide.
2. For the infrared band and window (8 to 14mm), tough front optics for Zinc sulfide thermal imaging systems. ZnS (single crystal zinc sulfide) is not widely available. The scattering is low in the common spectral range. The material’s bulk absorption and structural defects can be controlled, but the laser device can still be used for high-power purposes. It must use the chemicalbook polishing technique with the lowest damage level and the highest optical quality coating. Zinc sulfuride (ZnS), which oxidizes strongly at 300°C, displays plastic deformation around 500°C and is dissociated at approximately 700°C, can be used as a high-power laser device. In normal conditions, zinc sulfide window should not exceed 250degC.
3. Optical Coating Targets. X-ray screen. The watch’s luminous dial can be enhanced by adding traces or neothorium sodium. TV screen. paint pigments.
This product can cause severe corrosive reactions. poisonous. It can cause irritation to the skin. Protective equipment and clothing should be worn by all operators. The workshop must be well ventilated.
