Facts about Wolfram (2024)

Wolfram is known as one of the most difficult things found in nature.It is super dense and almost impossible to melt.Throne tungsten is a silver -white metal and when it is made a fine powder, it can be flammable and spontaneously inflamed.Naturally.Tungsten contains five stable isotopes and 21 other unstable isotopes.

Wolfram is used in many different ways because it is very strong and durable.It is very resistant to corrosion and has the highest melting point and the highest tensile strength for each element.The strength comes when it is made for connections.Soft.

Only facts

Here are the properties of tungsten, according toLos Alamos National Laboratory:

• Atomic number: 74
• Atomis symbool W
• Atomic Work: 183.84
• Smeltepunkt: 6.192 F (3.422 C)
• Boiling point: 10.030 F (5,555 C)

History

The first use of tungsten was more than 350 years ago.Chinese porcelain manufacturers used a tungsten that was a unique peach color, according toRoyal Society of Chemistry.

Much later, in 1779, Peter Woulfe investigated a mineral from Sweden and realized that it contains a new type of metal oxide oxide.However, none of these men are credited to the discovery of the element.

Juan and Fausto Elhuyar get the honor.During the seminar in Vergara in Spain, they investigated this mysterious metal.In 1783, the metal oxide from tungsten, and then, in contrast to the others, reduced to wolf tray metal by heating it with carbon.

Sources

Most tungsten sources can be found inDiep, South Korea, Bolivia, Groot -Britain, Russia and Portugal, as well as in California and Colorado.Although it is found in these many places, 80 percent of the World stock China is checked, according toBBC.

The element is of course found in the minerals Scheeliet, Tungwear, Huebnertie and Ferberiet.It is harvested from the minerals by reducing tungsten oxide with hydrogen or carbon.

Once picked up, tungled window is often mixed in alloys.The most difficult alloys are formed with diamonds.Diamonds are the only things that are more difficult than some tungsten alloys.

Applications

One of the most common and most difficult, tungsten compounds is tung window carbide.Because of the power when they are made for connections, the tungsten is used to harden and produce saw blades.It can take approximately. 10 minutes to cut only one exercise from tungsten with the help of a diamond cutting system, according to BBC.Some jewels also use tungsten carbide to make wedding tires and others.

Another tungsten connection that is particularly useful is tungsten -disulfid.It is used as a dry lubricant in temperatures as high as 932 degrees Fahrenheit (500 degrees Celsius), according toJefferson Lab.

Some other applications of tungsten include metal evaporation work, the production of paint, the production of seals from glass to metal and making electron and TV pipes.

The army uses tung window to produce balls and rockets that are used in "kinetic bombing."This type of attack uses a SuperDight material to violate armor instead of explosives.

The resistance to heat is useful when using it in the heating elements for electric ovens, spacecraft, welding and other applications at high temperature.It was also used to produce different types of lighting for this soil, the lighter the pear.In 1908, inventor William D. Coolidge discovered that Tungsten was an ideal filament.But nowadays most pears use more energy -efficient materials.However, it is still used in X -Ray filaments and in electrical contacts of various electronics.

Biologically, some bacteria use tungsten to reduce carbon acids to aldehydes.

You can just see there?

This element is used for deception."Wolfram may have no golden lust it weighs as much as gold -it will almost be correct," Amanda Simson, a university teacher in chemical technology at the University of New Haven, told Live Science. "Thus Tungsten were found in counterfeit Golden Stones."

Wolfram comes from a Swedish term,tungsten, it means "heavy stone".

The chemical symbol of Wolfram is a W that can seem strange because there is no W in the word.
