Zinc Sulfide ZnS Pulver Introduction
Zinc sulfide
An inorganic compound of the chemical name ZnS. The powder can be white, yellowish or a combination of both. It darkens in sunlight. While it can be stored in dry air for long periods, it may oxidize slowly to zinc sulfate if left in moist air. It’s usually formed by reacting hydrogen sulfide and zinc salt solution. Zinc sulfuride exhibits a high fluorescence efficiency and excellent electroluminescence functions. These include:
nano zinc sulfide
it has a distinctive photoelectric effect. It also presents excellent properties in the areas of electricity, magnetism mechanics and catalysis.
Zinc Sulfide ZnS Pulver: Physicochemical Characteristics
It is common for the Zn-S zinc sulfide chemical bonds to be covalent. Three types of the crystal are available: Low-temperature crystal (sphalerite) is the most common. Colorless cubic crystal is the Zn and S coordination numbers are 4, while the relative densities is 4.10. The crystal will transition to high temperature type at 1020. It’s a high-temperature zinc sulfide stability structure. High-pressure, which is the sodium chloride structural, Zn and S coordination number, are 6. The relative density is 5.21. The aqueous ZnS*H2O compound is white with a melting point at 1049 and relative density 3.98. Zinc sulfuride is insoluble and insoluble with water. It can also be insoluble and insoluble when acetic acid is used. But, zinc sulfide will dissolve in high concentrations of strong acids, such as hydrochloric, that release hydrogen sulfide. As the solubility of zinc sulfide is the same as that of hydrosulphuric, it can be found in dilute acids at the following equilibrium:
Zn2+H2S=2H+ZnS
The highly acidic zinc sodium solution does not allow hydrogen sulfide to precipitate zinc. When hydrogen sulfide gases is added to zinc salt solution, it is possible for zinc sulfide to precipitate, although the precipitation may not be complete. Ammonium Sulfide Solution can be used as a precipitant to precipitate zinc ions from zinc salt solution. The alkaline nature of ammonium-sulfide solutions can reduce the acidity. This method is used for air isolation in the industry. When exposed to sunlight, white zinc sulfide turns dark and can easily be oxidized into zinc sulfate. Zinc oxide can also be combined with zinc sulfide to make white paint pigments. Pure zinc sulfide does not emit light. As activators for zinc sulfide, trace manganese copper and silver can be added to the crystals of zinc sulfide. They will emit different colors after being irradiated. Zinc sulfuride can be found in many industries, including leather, dye, rubber and enamel.
Zinc sulfide This is both corrosive as well as poisonous. It can cause irritation to the skin. It is recommended that operators wear protective gear and overalls. Good ventilation is essential in the workshop.
Double decomposition method To make double-decomposition, add the zinc sulfate solution. Stir. You will see zinc sulfide, ammonium, and sulfur sulfate. Next, filter the solution and remove ammonium. Finally, use centrifugal separation to produce zinc sulfide.

Zinc Sulfide ZnS Pulver Applications
1. It can be used in analytical reagents as well as phosphor matrix and photoconductor materials.
2. Zinc sulfuride is used extensively in infrared windows and fairing. This metal is highly pure, easily soluble in water and has moderate density. Zinc sulfuride exhibits good consistency and uniformity in terms of its refractive indices. Although it has excellent image transmission in the range 8-12mm, some of its absorbs after 10um. With the longer wavelength, transmittance and scattering in the middle of the spectrum are higher. Zinc sulfide’s resistance to extreme environments is strong. The high hardness of Zinc Selenide and its fracture strength are two times that.
For zinc sulfide thermal image systems, infrared windows or thermal bands (between 8 and 14mm), tough front optics
Although single crystal zinc sulfide can be found, it’s not often. In the typical spectral range, scattering levels are very low. This laser can be used to produce high-power beams of light. However, it must not absorb bulk material or cause internal defects. It should also use the most effective polishing technology and coating technology.
Zinc sulfuride can oxidize at 300 degrees Celsius, show plastic deformation around 500 at approximately 500 and separates at roughly 700. In normal ambient temperatures, the temperature of zinc sulfide window should never exceed 250°C.
3. It is also used to create an optical coating target and a X-ray screen.
