Formation of Zinc Sulfide

Zn + S → ZnS

Overview

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.

Everyday Example

Glow-in-the-dark paint and watch dials historically contained zinc sulfide as the phosphorescent material.

Industrial Importance

Zinc sulfide is used in phosphorescent coatings, X-ray and television screens, and as a precursor to zinc metal extraction. Sphalerite mining is the primary source of zinc globally.
