Description
Tungsten Disulfide (WS₂) Nanopowder/Nanoparticles, Purity: 99.4+%, Size: 40–80 nm
Product Overview
Tungsten Disulfide (WS₂) Nanopowder is a high-purity, fine particle material with exceptional solid lubrication properties. With its unique lamellar structure and high thermal and chemical stability, WS₂ is widely used in extreme environments such as high temperature, high pressure, and vacuum. This nanomaterial also finds growing usage in catalysis, electronics, and energy storage systems due to its semiconducting and tribological characteristics.
