Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through sintering [7] for use in industrial machinery, engineering facilities, [8] molding blocks, [9] cutting tools, chisels, abrasives, armor ...
Plants, animals, and humans can all be affected by high cobalt concentrations in the environment. For plants, the uptake and distribution of cobalt is entirely species-specific. [ 8 ] In some species of plants, the overaccumulation of cobalt can lead to an iron deficiency .
The discovery of superhard tungsten tetraboride is further evidence for the promising design approach of covalently bonding incompressible transition metals with boron. While WB 4 was first synthesized and identified as the highest boride of tungsten in 1966, [52] it was only recognized as an inexpensive superhard material in 2011. [53]
A very important product of this type is tungsten carbide. [1] Tungsten carbide is used to cut and form other metals and is made from tungsten carbide particles bonded with cobalt. [2] Tungsten carbide is the largest and most important use of tungsten, [3] consuming about 50% of the world supply. [4]
The jewelry industry makes rings of sintered tungsten carbide, tungsten carbide/metal composites, and also metallic tungsten. [78] WC/metal composite rings use nickel as the metal matrix in place of cobalt because it takes a higher luster when polished. Sometimes manufacturers or retailers refer to tungsten carbide as a metal, but it is a ...

Tungsten carbide was commonly used in uranium-233 gun-type nuclear weapons used with artillery pieces for the same reason. [7] [8] In the W88 warhead, the primary uses a lightweight beryllium tamper, while the secondary has a heavyweight uranium-235 one. There are advantages to using a fissionable tamper to increase the yield.
