Tungsten Disulfide Industrial Grade 99%

Tungsten disulfide is gray fine particles or nano powder. It is a metal sulfide, which has property of semiconductor and diamagnetism. It is insoluble in water and alcohol, however dissolve in acid mixture of nitric acid and hydrofluoric acid and molten alkali. Tungsten(IV) sulfide is table at room temperature and pressure. Tungstic acid or tungsten is the raw material.

Tungsten Disulfide

CAS No.:12138-09-9 EINECS No.:235-243-3 Molecular Formula:WS2 Molecular Weight:247.97
Melting Point:1250℃ Density:7.5    


Tungsten(IV) sulfide is a new solid lubricant, which apply to lubricate at high temperature, high pressure, high load and high vacuum condition. When it adds in engineering plastics, self-lubricating parts turn out.

When mix it with some volatile solvent and spraying in metal surface, it can improve the service life of mould in impact forging and degree of finish of workpieces.

Tungstic Acid

Tungstic Acid is used in the production of tungsten metal and its derivatives, fire proofing fabrics and cellulose, reagent for uric acid, alkaloids, plasma proteins, blood sugar, clinical analysis of blood, textile (mordant, color resist) plastics.

Turpentine (also called spirit of turpentine, oil of turpentine, and wood turpentine) is a fluid obtained by the distillation of resin obtained from trees, mainly pine trees. It is composed of terpenes, mainly the monoterpenes alpha-pinene and beta-pinene. It is sometimes known colloquially as turps, but this more often refers to turpentine substitute (or mineral turpentine).
