What metal can withstand higher temperatures than tungsten?
Of all the metal elements in the periodic table, tungsten has the highest melting point, reaching 3,422 ℃ (boiling point 5,930 ℃). No metal element has a higher melting point than tungsten.The reason why tungsten has a very high melting point is related to its extremely high bond energy.
Tungsten is element 74, in the VIB group of the sixth period of the periodic table.Among tungsten's relatives, they have the most valence electrons of any metal, up to six, which means that each atom can form six metal bonds.Combined with other bonding parameters, tungsten is the most capable of bonding, making it the metal with the highest melting point.
However, there are other elements that can withstand higher temperatures than tungsten, and solid carbon can withstand temperatures of 3,627 ° c.But carbon has no fixed melting point (one standard atmosphere) because it sublimates at about 3627 ° c, compared with 4330 ° c (10.8 MPa) for carbon.So before it melts, the solid carbon will go straight into the gas phase.
Not only is there no metal known to man that does not melt at 10,000 degrees, but even those alloys do.So far, the most heat-resistant material manufactured by human beings is Ta4HfC5, which has a melting point of 4215 ℃. It is made of hafnium carbide and
tantalum carbide (melting point of nearly 4000 ℃), which have a higher melting point than tungsten.
Also, it should be noted that the melting point of the material depends on the pressure, and the higher the pressure, the higher the melting point will be.But when the temperature and pressure are greater than critical, the material becomes superfluid and loses its melting point.
