Black crystals or powders with metallic luster, hexagonal crystal structure. Insoluble in water. Soluble in hydrofluoric acid mixed acid. Soluble in molten alkali, insoluble in alcohol. It's stable in the air.
It has very low friction coefficient (0.03), high extreme pressure resistance and oxidation resistance (decomposition starts at 450 ºC in air, It is suitable for high temperature, high pressure, high vacuum, high load, high speed, high radiation, strong corrosion, ultra-low temperature and other harsh conditions.

1. Nano WS2 is mainly used as petroleum catalyst: it can be used as hydrodesulfurization catalyst, as well as polymerization, reforming, hydration, dehydration and hydroxylation catalyst
2. Nano WS2 is a new type of efficient catalyst for the preparation of inorganic functional materials
3.WS2 can be used as solid lubricant, dry film lubricant and self-lubricating composite material
4. Nano WS2 is a very important additive in producing high performance lubricating oil. Therefore, nano WS2 can be used as additives to synthesize new lubricating systems, which has broad application prospects.
5. Can also be used as fuel cell anode, organic electrolyte rechargeable battery anode and sensor anode, etc.
6. Used to make nano ceramic composites; It is a good semiconductor material.
