Formation of Zinc Sulfide
Zn + S → ZnS
Visão geral
Zinc and sulfur react when ignited to form zinc sulfide with a bright flash. Zinc sulfide is a luminescent material that glows when exposed to UV light. The mineral form, sphalerite, is the most important ore of zinc worldwide.

Exemplo do cotidiano
Glow-in-the-dark paint and watch dials historically contained zinc sulfide as the phosphorescent material.
Importância industrial
O sulfureto de zinco é utilizado em revestimentos fosforescentes, ecrãs de raios-X e televisão, e como pigmento branco. A esfalerite (ZnS) é o principal minério de zinco, processada em mais de 12 milhões de toneladas por ano.
