Ultrafine cemented carbide is a tool material developed in recent years. It is mainly based on ultrafine tungsten carbide powder and adds appropriate binder (such as Co) and grain growth inhibitor to produce high hardness, high wear resistance and high toughness cemented carbide material. Its performance is higher than conventional cemented carbide. It is used in hard-to-machine metal materials tools, micro-drills in electronic industry, precision dies and dies. Medical dental drills and other fields have shown more and more extensive application prospects.

Electrochromism refers to a stable and reversible change in the color or transmittance of a material under the action of an applied voltage or electric field. At present, electrochromic materials are considered to be one of the most promising smart materials, and it is expected to have great potential application value, such as smart window, automobile anti-glare rearview mirror and electrochromic display.

Magnetron is currently the most efficient microwave device, and it has a huge application market in the fields of civil heating and radiology. In recent years, with the rapid growth of microwave application markets such as radiology and container inspection, magnetrons continue to develop in the direction of high power, high frequency, miniaturization and low cost.

There are three main types of tungsten disulfide catalysts that have high chemical activity. They are hydrogenation active catalyst, non-polar functional material catalyst and photocatalyst. Tungsten Disulfide Catalysts have high application value in petroleum industry and other important fields.
