Tungsten carbide
A compound made of tungsten, carbon, and has a molecular structure of WC. The molecular weight is 195.85. Tungsten carbid is a black hexagonal crystal, with a metallic luster similar to that of diamond. Tungsten carbide conducts electricity well. Tungsten carbide can’t be dissolve in water or hydrochloric and sulfuric acids. However, it is easily soluble and dissolves in hydrofluoric and nitric acids. Tungsten carbide in its pure form is very fragile. However, if you add a tiny amount of cobalt or titanium to it, this can reduce the fragility.
Hydrogenated tungsten oxide WO3 can be reduced and processed to make tungsten powder. The average particle size is 35mm. Next, the mixture (containing tungsten powder and carbon) in an equal ratio is dried-blended using a ballmill for approximately 10 hours. Then it is pressure-formed under about 1t/cm2. Place the block of pressurized material in a graphite pan/crucible and heat to 14001700, or 15501650 if using an induction electrical furnace. The hydrogen stream will then produce tungsten carbide.
Since W2C can be generated from the beginning of the reactions, the reaction begins around the tungsten particle. Because the reaction is not complete (mainly because it is at a low temperature), both unreacted and intermediate W2C are left. The reaction must then be heated to the high temperatures mentioned above. The raw tungsten particle size should determine the temperature. A reaction can be initiated at temperatures between 1550-1650 °C for large particles that have an average size of 150 mm.
Tungsten carbid is used in the manufacture of cutting tools and wear-resistant parts. It also melts crucibles for various metals, such as cobalt, copper and bismuth.
Tungsten carbide is used for super-hard material as well as wear resistance. This can be combined with many other carbides to create a stable solution. WC-TiC-Co-cemented carbide tools have been extensively used. It is also possible to use as an addition of NbC–C or TaC–C ternary-system carbides. This will reduce the sintering temp and ensure excellent performance. It is also suitable for aerospace applications.
Tungsten carbide (WC) is made by combining tungsten anhydride, (WO3) and graphite at 1400-1600 degrees Celsius in a reducing environment. You can make dense ceramic products by either hot pressing or hot isostatically pressing sintering.

Tungsten Carbide
Utilizing metal tungsten or carbon as raw material, tungsten powder of an average particle size between 3 and 5 mm, and carbon black with the same quantity, are dried mixed and press molded. Then it is placed into graphite plates. W2C is produced in the hydrogen stream. The reaction continues at high temperatures to create WC. To make tungsten carbide, first tungstenhexacarbonyl must be thermally broken down in a CO atmosphere between 650 to 1000 degC. W2C is possible at higher temperatures than these.Hydrogenated tungsten oxide WO3 can be reduced and processed to make tungsten powder. The average particle size is 35mm.
