    What is Tungsten

    Tungsten is a metal, classified as a transition metal, and chemically tungsten is an element. The density of tungsten is 19.3 grams per cubic centimeter. Tungsten metal is found in the solid state at room temperature, with a melting point of 3410 °C (6170 °F) and a boiling point of 5660 °C (10220 °F). Tungsten has an atomic mass of 183.84 AMU, atomic number 74, and symbol (W). In the Periodic Table, tungsten is located in group 6, period 6 and block (D), its atom has 74 electrons, 74 protons, 110 neutrons and 6 energy levels.

    Tungsten metal was discovered in 1783 by two brothers named Juan Jose and Fausto Elhuyar, a Spanish chemist.

    Properties of Tungsten Metal

    • Tungsten is a silvery-white lustrous metal with a tinge of gray.
    • Tungsten is a hard metal.
    • Tungsten has the highest melting point of all metals.
    • Tungsten is chemically less reactive, it does not react with oxygen at ordinary temperatures, tungsten reacts with oxygen only at temperatures above 400 °C.
    • Tungsten metal becomes ductile at high temperatures, so thin wires can be made from it.
    • Tungsten dissolves in nitric acid and aqya regia.
    • Tungsten is a good conductor of electricity and heat.
    • Tungsten powder and tungsten dust are highly flammable and explosive.
    • All tungsten compounds are toxic.

    Uses of Tungsten Metal

    • Tungsten is used to make the filament of fluorescent bulbs, these bulbs emit a lot of heat along with light, these types of bulbs are not very energy efficient, so nowadays LED bulbs are used instead.
    • Tungsten is used in arc welding electrodes.
    • Tungsten is used as a heating element in electric furnaces.
    • Parts of spacecraft, rocket engines, missiles and high-speed fighter aircraft that withstand high temperatures are made from tungsten.
    • Such alloys are made by adding tungsten to steel, which maintains its strength even at high temperatures.
    • Tungsten carbide is an extremely hard compound, it is used for making high speed cutting tools, drills etc. that work at high temperatures.
    • Tungsten disulfide is a dry lubricant, it is used for lubrication at high temperatures.
    • Tungsten alloys are used in radar equipment.
    • Tungsten is used as an emitter coil in an X-ray machine.
    • Tungsten is used in microchip technology and liquid crystal displays.

    Interesting facts about tungsten metal

    • Tungsten is the 56th most abundant element in the Earth's crust.
    • The largest production of tungsten in the world is done in China, which accounts for more than 60% of the total tungsten production in the world.
    • Long-term exposure to tungsten can cause irritation of the eyes and lungs, difficulty breathing, and itching and swelling of the skin.
    • Scheelite and wolframite are the main minerals of tungsten.
