Tungsten carbide is immensely hard and is very important to the metal-working, mining and petroleum industries. It is made by mixing tungsten powder and carbon powder and heating to 2200°C. It makes excellent cutting and drilling tools, including a new ''painless'' dental drill which spins at ultra-high speeds.
· Tungsten (W) is a refractory metal that has a melting point of 3370 "C. Tungsten, also known as wolfram, belongs to group 6 of the periodic table, along with Cr and Mo. It is an economically important metal. Learn more @Byju''s

· Having the highest melting point of any known metal, at 6192°F, obviously tungsten would be very difficult to melt. In theory, anything can be melted if you apply enough heat. However, for commercial purposes, the high tungsten melting point makes liquid tungsten a virtually impossible proposition.
Tungsten reacts with halogens, forming the corresponding tungsten halides. Tungsten will react with fluorine at room temperature, whereas the remaining halogens requires heat. For the most part, tungsten (VI) halides are formed, but under controlled conditions, chlorine can also form tungsten (V) chloride.
Tungsten, or wolfram,   is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a ...
