Top 10 Zinc Sulphide Suppliers in the world 2025

Introduction to Zinc Sulphide

Zinc sulphide (ZnS) is an inorganic compound that occurs in nature as the minerals sphalerite (also known as zinc blende) and wurtzite. It is an important industrial material with a wide range of applications.

One of the most common uses of zinc sulphide is in the production of phosphors. Phosphors are materials that can emit light when excited by various forms of energy, such as ultraviolet light, cathode rays, or X - rays. Zinc sulphide - based phosphors are widely used in cathode - ray tubes (CRTs), which were once the dominant technology for televisions and computer monitors. They are also used in fluorescent lamps, electroluminescent displays, and scintillation detectors.

In the field of optics, zinc sulphide is used as an infrared optical material. It has good transparency in the infrared region of the electromagnetic spectrum, making it suitable for applications such as infrared windows, lenses, and prisms. Zinc sulphide is also used as a pigment in paints, plastics, and rubber. It provides good hiding power and whiteness, and is resistant to heat, light, and chemicals.

In addition, zinc sulphide has applications in the semiconductor industry. It is a wide - bandgap semiconductor material with potential applications in optoelectronic devices, such as light - emitting diodes (LEDs) and photovoltaic cells.
