TUNGSTEN Meaning and
Definition
-
Tungsten is a chemical element with the symbol W and the atomic number 74. It is a highly dense, strong, and hard metal that is found naturally on Earth. Tungsten has a silvery-white appearance and is known for its exceptional heat resistance and high melting point, making it suitable for various applications.
In its pure form, tungsten is brittle and difficult to work with, but when combined with small amounts of other metals, it becomes more malleable. It is often used as an alloy in the creation of strong and high-temperature materials, such as tool steels, superalloys, and heating elements. Tungsten alloys are also utilized in electrical and electronic devices due to their high electrical conductivity.
Additionally, tungsten is a key component in the production of filaments for incandescent light bulbs and electron microscope filaments, as it has a high emission capability. Its density makes it an ideal material for applications requiring weight balancing, such as in aircraft and Formula One car components.
The name "tungsten" derives from the Swedish words "tung" and "sten," which translate to "heavy stone," as tungsten ores are notably dense. This element is commonly referred to as "wolfram" in many countries, which originated from its German name. Tungsten holds significant importance in various industrial sectors due to its unique properties, making it a valuable and versatile element in modern technology and manufacturing.

Etymology of TUNGSTEN
The word "tungsten" comes from the Swedish term "tung sten", which translates to "heavy stone". The name was given to the element because of its high density and weight. The word "tung" means "heavy" in Swedish, and "sten" means "stone". The element itself was discovered in the late 18th century by Swedish chemist Carl Wilhelm Scheele and later isolated in 1783 by his compatriot and fellow chemist, Peter Jacob Hjelm.
