The chemical element Wolframium, also known as Tungsten, is a transition metal with the atomic number 74. Its name is derived from the mineral wolframite, in which it was first discovered. The correct spelling of the word is "Wolframium," with the IPA phonetic transcription [wʊlˈfræmiəm]. The first syllable "wul" sounds like "wool," and the second syllable "fram" sounds like "from." The "ium" ending indicates that it is a metallic element. Due to its high melting point and density, Wolframium is used in a variety of industrial applications such as light bulb filaments and electrical contacts.
Wolframium, also known as tungsten, is a chemical element represented by the symbol W in the periodic table, with an atomic number of 74. It is a hard, dense, and steel-gray metal that is naturally found in minerals such as scheelite and wolframite. The name "wolframium" is derived from the German word "wolfram," meaning "wolf's foam," which refers to the dense mineral it was originally extracted from.
Wolframium possesses a high melting point of 3,422 degrees Celsius, making it one of the highest melting metals. It is also known for its exceptional strength, excellent thermal and electrical conductivity, and resistance to corrosion or oxidation. Due to these properties, it finds extensive applications in various industrial sectors.
One of the primary uses of wolframium is in the production of filaments for incandescent light bulbs and electron emission devices. Its robustness and resistance to high temperatures make it a suitable material for these applications. Additionally, wolframium is employed in the manufacturing of high-speed steel alloys, which are esteemed for their durability and cutting abilities in tools and machinery.
Moreover, wolframium is significant in the field of nuclear energy. It serves as a crucial component in the construction of reactor cores, as it can tolerate the extreme conditions and high temperatures associated with nuclear power generation. Furthermore, its ability to absorb and disperse neutrons effectively makes it an essential material for shielding and other nuclear applications.
In conclusion, wolframium is a robust and versatile metal with exceptional physical and chemical properties. Its high strength, melting point, and resistance to corrosion contribute to its diverse range of industrial applications, from light bulb filaments to nuclear reactors.
The word "wolframium" has its etymology rooted in the element tungsten (atomic number 74). In the early 19th century, the Swedish chemist Carl Wilhelm Scheele discovered an oxide of tungsten which was then called "tungstic acid". Four years later, the element itself was isolated by his countryman, the Swedish chemist and mineralogist, Carl Johan Wilcke. Wilcke named the new element "tungsten" which is derived from the Swedish words "tung" (heavy) and "sten" (stone), referring to the element's high density.
In some languages, however, the element tungsten is known by a different name.
