Tungsten disulfide powder has excellent lubricity and high temperature resistance, so it is usually added to lubricating materials. The lubricating materials with tungsten disulfide powder have better lubrication performance and longer service lives.

Tungsten, with its excellent high temperature resistance, high strength and hardness, is an irreplaceable key material in many fields, especially in the field of national defense, aviation and aerospace. Compared with pure tungsten, alumina coated tungsten and tungsten alloy can greatly increase the strength of tungsten, refine grain size, reduce particle size, increase the toughness and tensile strength of materials.

Tungsten disulfide powder with low friction coefficient and good lubricating performance is considered as one of the ideal materials for parts coating. Small parts can be coated with it directly by means of a vibration bowl.

In view of the problems existing in the preparation of tungsten oxide nanowires and their gas sensing applications, researchers have prepared tungsten oxide nanowires gas sensing materials in a wide range by simple hydrothermal method, and then provided a tungsten oxide nanowire sensor with high sensitivity, good repeatability and high stability for H₂, CO and NH₃. The operation process is as follows:
