Tungsten is a nonferrous metal and an important strategic metal. Tungsten ore was called "heavy stone" in ancient times. In 1781, Swedish chemist Carl William Scheyer discovered scheelite and extracted a new element acid - tungstic acid. In 1783, the Spanish man De Pulya discovered that wolframite also extracted tungstic acid from scheelite. In the same year, tungsten powder was first obtained by reducing tungsten trioxide with carbon, and the element was named. The content of tungsten in the crust is 0.001%. 20 kinds of tungsten minerals have been found. Tungsten deposits are generally formed with the activity of granitic magma. After smelting, tungsten is a silvery white and shiny metal with a very high melting point and hardness. Atomic number 74. The steel is gray or silver white, with high hardness and melting point, and is not subject to air erosion at room temperature; It is mainly used to manufacture filament and high-speed cutting alloy steel, superhard mold, and also used in optical instruments and chemical instruments [tungsten; wolfram] -- the wire drawn from the element symbol W. Tungsten rod, which can be used as the filament in electric bulbs, electronic tubes, etc.
