2025 Top 10 Zinc Sulphide Manufacturers in the world

Introduction to Zinc Sulphide

Zinc sulphide (ZnS) is an inorganic compound that exists in two main crystalline forms: sphalerite (cubic) and wurtzite (hexagonal). It is a widely used compound with a variety of applications.

In the field of optics, zinc sulphide is used as an infrared optical material. It has good transmittance in the infrared region, making it suitable for applications such as infrared windows, lenses, and prisms in thermal imaging systems. In the pigment industry, zinc sulphide is an important white pigment. It has high hiding power and good chemical stability, and is often used in paints, coatings, plastics, and rubber to improve their whiteness and opacity. Additionally, zinc sulphide is used in the production of phosphors. When doped with various activators, it can emit different colors of light under ultraviolet, cathode - ray, or X - ray excitation, which is widely used in fluorescent lamps, cathode - ray tubes, and scintillation counters.
