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 with 3.98g/cm3 density and a melting point at 1700°C, is found in sphalerite. Insoluble in water; soluble in acids. You can see the sun 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.

1. Zinc sulfuride (ZnS), is used widely in making infrared fairings, windows, and optical components. It has high purity, is insoluble in water, moderate densities, and is easy to process. 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 can still be used under the conditions of using the chemicalbook technology to minimize damage and to provide the best optical quality. 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 250 degrees Celsius.
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 toxicity. poisonous. It can cause irritation to the skin. Operators should wear protective gear and work clothes. The workshop must be well ventilated.
