Zinc Sulfide is an inorganic compound with the chemical formula ZnS and CAS Number 1314-98-3. It is commonly supplied as a white to pale yellow powder, although its appearance may vary depending on its purity, particle size, and crystalline structure. It occurs in two primary crystalline forms: sphalerite (cubic) and wurtzite (hexagonal).

Zinc Sulfide is valued for its chemical stability, optical properties, and role as a source of zinc and sulfide ions in specialised chemical applications. Common laboratory applications include inorganic chemistry experiments, material science research, preparation of zinc-containing materials, and studies involving metal sulfides. It is also used in specialised applications such as phosphor materials, optical materials, pigments, and semiconductor research.

Its distinctive optical and physical properties make Zinc Sulfide useful in materials science, solid-state chemistry, and general laboratory research. The appropriate grade, purity, particle size, and crystalline form should be selected according to the requirements of the intended application.

KSFE Malaysia supplies laboratory chemicals and scientific products for research institutions, educational facilities, and general laboratory applications.

Safety Note: Zinc Sulfide should be handled carefully to avoid generating or inhaling dust. Avoid contact with the eyes and skin, and use appropriate personal protective equipment, including suitable respiratory protection where dust exposure may occur. Avoid contact with strong acids, as this may release toxic hydrogen sulfide gas. Handle and store the material in a suitable, well-ventilated area and follow the supplier's Safety Data Sheet (SDS) for proper handling, storage, and disposal.
