To prepare tungsten disulfide lubricant for isothermal forging, three steps are needed: take the compositions of emulsion according to proportion, disperse the compositions uniformly and add nano tungsten disulfide into the emulsion. The preparation process is strict but easy.

Tungsten disulfide lubricant used in isothermal forging is formed by adding nano tungsten disulfide to emulsion. It is a kind of new lubricating material with injection performance, insulating performance, lubricating performance and mold unloading performance.

Nano tungsten disulfide can be used in isothermal die forging to reduce the friction loss between working parts and improve their service lives. A dense protective film of tungsten disulfide will be formed during the forging process.

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 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.

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.

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:

Scheelite is a troublesome raw material in tungsten smelting. With the popularization of alkali pressure leaching technology in the last century, the production capacity and scale of scheelite smelting have been greatly improved, and the technology has been further mature. Because of the excessive alkali process, although most of the alkali is consumed in the leaching process, the residual alkali in crude sodium tungstate solution is still very high after the reaction.

Tungsten oxide is a kind of transition metal oxide, which belongs to n-type semiconductor and has a wide range of applications. At present, a large number of studies have found that tungsten-based oxides not only act as catalysts, electrochromic, solar energy absorption materials and invisible materials, but also have the characteristics of semiconductor functional materials such as thermal, pressure and gas sensitivity.

As a member of transition metal oxides, tungsten oxide (WO₃) is an indirect bandgap n-type semiconductor material with a band gap of 2.2-2.8eV. It has good absorption of visible light, so it is a very promising semiconductor photocatalyst. However, at present, there are many methods to prepare tungsten trioxide, which have poor controllability and difficult to grasp the photocatalytic performance.
