Tungsten's high melting point makes tungsten a good material for applications like rocket nozzles, for example in the UGM-27 Polaris submarine-launched ballistic missile. [82] Tungsten alloys are used in a wide range of applications, including the aerospace and automotive industries and radiation shielding. [ 83 ]

Its high melting point makes tungsten a good material for applications like rocket nozzles, for example in the UGM-27 Polaris. [24] Some of the applications of tungsten are not related to its refractory properties but simply to its density. For example, it is used in balance weights for planes and helicopters or for heads of golf clubs.
The table below shows some of the parameters of common superconductors.X:Y means material X doped with element Y, T C is the highest reported transition temperature in kelvins and H C is a critical magnetic field in tesla.
Structurally, they resemble sulfates. Six-coordinate, octahedral tungsten dominates in the polyoxotungstates. In these compounds, the W–O distances are elongated. [1] Some examples of tungstate ions: [3] HWO − 4 (hydrogentungstate) [3] polymeric W 2 O 2− 7 ions of various structures in Na 2 W 2 O 7, Li 2 W 2 O 7 and Ag 2 W 2 O 7 [4] [W 7 ...
In a cello (example shown above) or a viola the C-string sometimes incorporates tungsten; its high density permits a smaller diameter string and improves responsiveness. [128] Some uses of heavy metals, including in sport, mechanical engineering, military ordnance, and nuclear science, take advantage of their relatively high densities.
The analysis detected elements such as nickel, copper, zinc, tin, mercury, gold, lead and a big surprise: tungsten, which hadn’t even been described at the time. It’s possible that Brahe ...
Sodium tungsten bronze is a form of insertion compound with the formula Na x WO 3, where x is equal to or less than 1. So named because of its metallic lustre, its electrical properties range from semiconducting to metallic depending on the concentration of sodium ions present; it can also exhibit superconductivity .
