nature: 
-Tungsten boride is an intermetallic compound. 
-It has very high hardness and wear resistance, harder than ordinary steel. 
-It is a brittle material that is prone to fracture. 
Manufacturing method: 
-Tungsten boride is usually prepared by high-temperature solid-state reaction. 
-Mix metal tungsten and boron compounds (such as boron powder) evenly. 
-Then, at high temperatures (usually above 2000 ° C), the reaction is carried out under solid-phase conditions to generate tungsten boride. 
Purpose: 
-Tungsten boride is mainly used in the manufacture of high-speed cutting tools and other applications that require superhard materials. 
-It can be used to process various hard materials such as steel, cast iron, and alloys. 
-Tungsten boride is also used to manufacture cutting-edge electronic devices and thin film materials in the semiconductor industry. 
It has wide applications in aviation, aerospace, semiconductor, and electronics fields, such as being used as thermal barrier coatings, high-temperature thermocouples, tungsten wire heaters, semiconductor epitaxial substrates, and ceramic wear-resistant parts. It is a ceramic material with extremely high hardness and good corrosion resistance, widely used in various industrial and scientific research fields under extreme environments such as high temperature, high pressure, and strong magnetic fields. Has high hardness, strength, and melting point similar to diamond. It also has good conductivity and thermal conductivity, and can be used as an electric heating element and heat sink at high temperatures.
