Top 10 ZnS Powder Suppliers in the world 2025

Introduction to ZnS Powder

Zinc sulfide (ZnS) powder is a significant 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 known for its luminescent properties, which make it useful in phosphors for cathode - ray tubes, fluorescent lights, and electroluminescent devices.

In addition to its optical and luminescent applications, ZnS powder is used as a pigment in paints, plastics, and rubber due to its white color and good hiding power. It is also an important semiconductor material, with potential applications in optoelectronic devices, solar cells, and sensors. The high chemical stability of ZnS powder makes it suitable for use in harsh environments, and its low toxicity makes it a relatively safe material for various industrial applications.
