Product Name:Tungsten Disulfide
English Name:Tungsten Disulfide
CAS No.:12138-09-9
Aliases:Tungsten(IV) sulfide, Tungsten sulfide
Molecular Formula:WS2
Physical Properties:Grey-black to blue-grey powder with metallic luster and a graphite-like layered structure. Density approx. 7.5 g/cm³. Thermal decomposition temperature approx. 1250°C; stable in air up to approx. 450°C. Almost insoluble in water and dilute acids.
Uses:Used as a solid lubricant under high temperature, high load, vacuum and radiation conditions, and suitable for formulating specialty greases/pastes, modifying polymer composites, preparing dry-film lubricating coatings, and serving as a metalworking additive. Nano-scale tungsten disulfide has broad prospects in catalysis, energy storage and electronic devices, and can also be used as an electrocatalyst or a component of battery electrode materials.
Technical Specifications:
Appearance: grey-black to blue-grey powder with metallic luster.
WS2 content: ≥99.0%, higher purity grades available on request.
Typical particle size: customizable from 1.0 μm to 20 μm, or nano-scale.
Density: approx. 7.5 g/cm³.
Moisture content: ≤0.5%.
