Naturally occurring tungsten consists of four stable isotopes (182 W, 183 W, 184 W, and 186 W) and one very long-lived radioisotope, 180 W. Theoretically, all five can decay into isotopes of element 72 by alpha emission, but only 180 W has been observed to do so, with a half-life of (1.8 ± 0.2) × 10 18 years; [36] [37] on average, this yields ...
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 ...
Tungsten's high density and strength are also key properties for its use in weapon projectiles, for example as an alternative to depleted Uranium for tank gun rounds. [23] Its high melting point makes tungsten a good material for applications like rocket nozzles, for example in the UGM-27 Polaris. [24]
The SAE designation for all tungsten steels consist of four numbers beginning with the number 7, in the format 7XXX. Tungsten steel also has a greater density than regular stainless steel, tungsten steel, also known as cemented carbide has a density of 14.8 g/cm^3. whereas regular stainless steel maintains a density of 7.9 g/cm^3
Additionally in the 19th century tungsten sulfides were sparingly used as lubrication for machining. Wolframite is also used to make tungstic acid which is used in the textile industry. [14] A major modern day use of tungsten is as a catalyst for various chemical reactions. One such catalytic use of tungsten is as a hydrocracking catalyst which ...

The dominant use of sodium tungstate is as an intermediate in the extraction of tungsten from its ores, almost all of which are tungstates. [1] Otherwise sodium tungstate has only niche applications. In organic chemistry, sodium tungstate is used as catalyst for epoxidation of alkenes and oxidation of alcohols into aldehydes or ketones .
