What is Tungsten:
Tungsten, also known as wolfram, is a chemical element with the chemical symbol W and atomic number 74.
The word tungsten comes from the Swedish language tung sten directly translatable to heavy stone,
[3] though the name is volfram in Swedish to distinguish it from Scheelite, which in Swedish is alternatively named tungsten.
A hard, rare metal under standard conditions when uncombined, tungsten is found naturally on Earth only in chemical compounds.
It was identified as a new element in 1781, and first isolated as a metal in 1783. Its important ores include wolframite and scheelite.
The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all the elements.
Also remarkable is its high density of 19.3 times that of water, co***rable to that of uranium and gold, and much higher (about 1.7 times) than that of lead. |
