Vacuum coating material Zinc Sulfide Insoluble in water, soluble in acid. See the darkening of the sun. Change to zinc sulfate in a long time in humid air. Generally obtained by the action of hydrogen sulfide and zinc salt solution. If a small amount of Cu, Mn, or Ag is added to the crystal ZnS as an activator, after exposure to light, different colors of fluorescence can be emitted. Used as analytical reagents, coatings, paints, white and opaque glass, filled with rubber, plastic, and used to prepare phosphors. It is prepared by co-heating sulfur and zinc. Relative density 4.087
