Zinc sulfide
Zinc sulfide is a chemical compound. Its chemical formula is ZnS. It contains zinc and sulfide ions.
Properties
Zinc sulfide is white when pure. It does not dissolve in water. It can burn at a high temperature to make sulfur dioxide and zinc oxide. It reacts with strong acids to make hydrogen sulfide.
Preparation
Zinc sulfide can be made by igniting a mixture of powdered zinc and sulfur. Another way of making it is to react hydrogen sulfide with a zinc compound.
Uses
Zinc sulfide is used to convert ultraviolet light to visible light. It can be doped with copper to make it glow in the dark.
Zinc Sulfide Media
Sphalerite, the more common polymorph of zinc sulfide
Wurtzite, the less common polymorph of zinc sulfide
Mixtures of zinc and sulfur react pyrotechnically, leaving behind zinc sulfide.
