Physical and chemical properties

physical property

White or slightly yellow powder. When burned in H2S gas, it transforms into crystals. α The variant is a colorless hexagonal crystal with a density of 3.98g/cm3 and a melting point of 1700 ℃; β The variant is a colorless cubic crystal with a density of 4.102g/cm3, which is transformed into α Type. It exists in sphalerite. Insoluble in water and easily soluble in acids. The color darkens when the sun shines.

chemical property

Transformed into zinc sulfate after prolonged exposure to humid air. It is generally obtained by the interaction of hydrogen sulfide and zinc salt solution. If trace amounts of Cu, Mn, Ag are added as activators to the crystal ZnS, it can emit fluorescence of different colors after illumination. Used as analytical reagents, coatings, paints, white and opaque glass, filled with rubber, plastics, and for the preparation of fluorescent powders.

Purpose

Used as a matrix and photoconductor material for analytical reagents and fluorescent powders; It is also used in the manufacturing of dyes, coatings, pigments, glass, curing oils, etc.
