Abstract After a historical excursus, the basic properties of tungsten are summarized, followed by selected classes of inorganic compounds (tungsten halides and oxyhalides, tungsten oxides, Magne ́li phases and tungsten bronzes, iso- and heteropolyoxotungstates).
Tungsten can combine with oxygen, fluorine, chlorine, bromine, iodine, carbon, nitrogen, sulfur, etc. at high temperatures, but not with hydrogenation. Tungsten reacts with carbon at high temperatures, which can produce hard, wear-resistant, and insoluble tungsten carbide.

Tungsten steel is any steel that has tungsten as its alloying element with characteristics derived mostly from the presence of this element (as opposed to any other element in the alloy). Common alloys have between 2% and 18% tungsten by weight along with small amounts of molybdenum and vanadium which together create an alloy with exceptional ...
Tungsten is a hard metal with a lustrous and silvery white appearance. It is resistant to oxidation and attack by acids and alkalis. It is a bulky metal and has the highest melting point of any metal. The chemical name of tungsten is Wolfram, represented by W.
Characteristics. Physical properties. In its raw form, tungsten is a hard steel-grey metal that is often brittle and hard to work. Purified, monocrystalline tungsten retains its hardness (which exceeds that of many steels), and becomes malleable enough that it can be worked easily. [18] .
