Tungsten is a chemical element with the atomic number 74 and symbol W. It is a dense, grayish-white metal that is extremely hard. Tungsten has the highest melting point and boiling point. Tungsten is a hard metal that ranks between 7.5 and 8 on the Mohs hardness scale. However, tungsten carbide is much harder than tungsten.

To prepare tungsten carbide, we used the exothermic reaction between tungsten oxide, carbon (black), and magnesium metal: WО 3 + Mg+ С + R → WC∙MgO∙Mg + R'+ Q. where R is a regulating additive. The temperature of this process exceeds 3000°C; it can cause decomposition of the forming tungsten carbide.
