2025 10 Leading ZnS Powder Suppliers in the world

Introduction to ZnS Powder

Zinc sulfide (ZnS) powder is an important inorganic compound with a wide range of applications. It exists in two main crystalline forms: sphalerite (cubic) and wurtzite (hexagonal). ZnS powder has excellent optical properties, such as high refractive index and good transparency in the infrared region. It is also a semiconductor material with a wide band - gap, which makes it suitable for various optoelectronic and photonic applications.

ZnS powder is commonly used in the production of phosphors for cathode - ray tubes, fluorescent lamps, and electroluminescent devices. It is also used as a pigment in paints, plastics, and rubber due to its high whiteness and hiding power. In addition, ZnS powder is used in the field of infrared optics, such as infrared windows and lenses, because of its good infrared transmittance.
