What is Zinc sulfide?
Zinc sulfide is an inorganic compound with a chemical formula of ZnS. It is a white or slightly yellow powder, and the color becomes darker when seen. It is stable in dry air, and when it is placed in humid air for a long time or contains moisture, it will gradually oxidize to zinc sulfate.
Zinc sulfide is a white or slightly yellow powder, which turns into crystals when burned in H2S gas. The alpha variant is a colorless hexagonal crystal with a density of 3.98g/cm3 and a melting point of 1700°C. The beta variant is a colorless cubic crystal with a density of 4.102g/cm3, which is transformed into the alpha form at 1020°C. Zinc sulfide exists in sphalerite, is insoluble in water, and easily soluble in acid, and the color becomes dark when seen in sunlight.
How is Zinc Sulfide ZnS Powder Produced?
Zinc sulfide is usually made from waste materials for other purposes. Typical sources include smelters, slag, and pickling liquor. It is also a by-product of ammonia synthesis from methane, where zinc oxide is used to remove hydrogen sulfide impurities in natural gas.
What is zinc sulfide used for?
Zinc sulfide can be used as an analytical reagent, phosphor matrix, photoconductor material, and also used in the manufacture of dyes, coatings, pigments, glass, and curing oil.
Is zinc sulfide harmful? 
Zinc sulfide is toxic and can irritate the skin. Operators must wear work clothes and protective equipment.
Zinc sulfide is white to off-white or light yellow powder. See the light darken. It is stable in dry air, and when it is placed in humid air for a long time or contains moisture, it will gradually oxidize to zinc sulfate. Soluble in dilute inorganic acid, soluble in alkali, insoluble in water. The relative density is 3.98 (α type), (d25) 4.102 (β type).
