Tungsten carbide scriber is a fitter tool that is mainly applied for scribing on the surface of different workpieces such as steel plates, and ceramic tiles. The scriber made of high quality tungsten carbide is often used in conjunction with guide tools including steel rulers and scribing templates, etc.

How to prepare tungsten disulfide nanoparticles? At present, the flower-shaped WS2 nanoparticles are mainly prepared by hydrothermal method. While this method has the disadvantage of low yield, which is not conducive to mass production. So, some experts have proposed a simple process - high temperature vulcanization method - to prepare flower-shaped WS2 nano particles. The high purity WS2 nano particles are prepared by this method with low cost and high yield, so it is expected to be used in large-scale industrial production.

Tungsten disulfide is a new type of graphene-like two-dimensional material, which has great application potential in electrical devices, energy, biology and composite materials.

Tungsten disulfide catalyst has excellent dispersibility and catalytic activity in both polar and non-polar catalytic reaction systems. Some experts formulate the tungsten source, sulfur source, reducing agent, ionic liquid and deionized water into the initial reaction mixture in a certain order and method, and then crystallize it under hydrothermal conditions in a sealed high-pressure reactor. After filtering, washing and drying the crystallized product, a tungsten disulfide catalyst is obtained.
