Zinc sulfide (ZnS) belongs to an inorganic compound, and the appearance is a white or slightly yellow powder, see the light color becomes dark. Stable in dry air, long placed in wet air or containing water, the gradual oxidation to zinc sulfate. Its molecular weight is 97.445, and the melting point is 1700℃; the water solubility: is insoluble, and its physical properties are: white or slightly yellow powder. But burning in H2S gas is converted into crystals. The α variant is a colorless hexagonal crystal with a density of 3.98 g/cm3 and a melting point of 1700℃; the β variant is a colorless cubic crystal with a density of 4.102 g/cm3 converted to α at 1020℃. Prespresent in spblerite. Insoluble in water and easily soluble in acid. See that the sun turns dark—chemical properties: long in humid air into zinc sulfate, generally from the action of hydrogen sulfide and zinc salt solution. If a trace amount of Cu, Mn, and Ag is added to the crystal ZnS as an activator, different colors can be emitted after illumination. Used as analytical reagents, coatings, paint, white and opaque glass, filling rubber, plastics, and for the preparation of phosphors. Main uses of zinc sulfide Use as a substrate for analytical reagents and phosphors; and for manufacturing dyes, coatings, pigments, glass, curing oil, etc. Zinc sulfide is a semiconductor compound material composed of sulfur and zinc. The molecular formula is ZnS, the molecular weight of 97.45, the melting point of 1020℃ (15MPa), the white crystal, a lattice constant of 0.547nm, hexagonal crystal type, and a density of 4.08 g/cm3. Almost insoluble in water but soluble in acid. Long-term placement in moist air transforms into zinc sulfate. The bandwidth of 3.6 eV is the widest of-family compound semiconductor materials. So it can be made into blue light-emitting tubes. Powdered zinc sulfide is the most important field luminescent material, a photo-fluorescent material used for preparing imaging tube fluorescent screens, scoreboard displays, etc. The window and coating material in the infrared light Chemicalbook learning material is also used. Most zinc sulfide for phosphor is made by solution, characterized by large yield and low cost. The high pure zinc sulfide synthesized directly through the gas phase is crystallized in a needle shape and is used to prepare the high-performance coating material and single crystal raw material. Zinc sulfide single crystal can be grown by high-pressure single-crystal furnaces and chemical gas phase transport (CVD). Zinc sulfide sheets for optical materials can be prepared by them pressing and the CVD method, which is widely used in window materials of lasers. In recent years, the preparation of zinc sulfide film materials mostly adopts the metal-organic chemical vapor deposition method; due to the low growth temperature, the generated film has good integrity and few defects, and it is easy to prepare heterojunction photoelectronic devices.
Price of zinc sulfide The different price of zinc sulfide purity is also different. The market price of zinc sulfide is in the process of dynamic change. The price of zinc sulfide can be found on our company's official website. If you need it, you can ask us at any time.
