The word "tungsten" comes from the Swedish words "tung" and "sten," which mean "heavy" and "stone," respectively.
Meaning and Origin
Tungsten is a chemical element with the symbol W and atomic number 74. It is a hard, brittle, grayish-white metal. Tungsten is the heaviest of the non-radioactive elements and has the highest melting point of all metals at 3,422 °C (6,192 °F).
Tungsten was first identified in 1781 by the Swedish chemist Carl Wilhelm Scheele. Scheele discovered tungsten in a mineral called scheelite, which contains tungsten trioxide. Scheele named the element "tungsten" because of its heavy weight and dark color.
Tungsten is found in a variety of minerals, including scheelite, wolframite, and hubnerite. The main commercial source of tungsten is wolframite. Tungsten is a valuable metal because of its high melting point and strength. It is used in a variety of applications, including the production of high-speed steel, cutting tools, and welding electrodes.
