Physical properties of Tungsten, its raw form is a gray-white metal and is often brittle and reluctant. But, in its purest form it is still to be easily processed. Usually though it contains preparational a low carbon and oxygen impurities, which gives it a significant tungsten hardness and brittleness. Tungsten is a unique metal that several high-performance reasons. It is one of the hardest metals and grūtkūstošākajiem. Its melting point is 3422 C, which is one of the highest rates, the higher is the only carbon. While the boiling point - approximately 5700 C, which is approximately the same as the sun's surface temperature. Tungsten is 19:25 g/cm3 density, which makes it one of the most serious metāliem.Tāpat tungsten preparational has the lowest vapor pressure of all metals in the middle, very high compaction creator, very high for thermal resistance, and high thermal and electrical conductivity, as well as the lowest coefficient of expansion of metals middle and high tensile strength. Tungsten is the most important metal for devices task is related to heat and light, not only to its high electron emissivity (caused by other elements to), but also thermal and chemical stability reasons. Chemical preparational properties of chemical compounds Tungsten "kick attacks" from both the oxygen and acids and alkalis. The usual oxidation state of tungsten is +6, but it is also found in all other oxidation states from -1 to +6. ...
