What metal is more resistant to high temperature than tungsten?

Of all the metal elements in the periodic table, tungsten has the highest melting point, with a melting point of 3,422 ℃ (boiling point of 5,930 ℃). No other metal element has a higher melting point than tungsten. The high melting point of tungsten is related to the extremely high bond energies of metal bonds.

Tungsten is element 74, which is in the sixth period of the periodic table. Among tungsten's relatives, they have the highest number of valence electrons in a metal, up to six, meaning that each atom can form six metal bonds, so the group's bond energies are extremely high, leading to a very high melting point. Combined with other bonding parameters, tungsten has the strongest bonding ability, making it the metal with the highest melting point.

However, there are other elements that can withstand higher temperatures than tungsten, and solid carbon elements can withstand temperatures of 3627 ℃.But carbon has no fixed melting point (1 standard atmosphere), because it sublimes at about 3,627 ° c, whereas carbon's triple point temperature is 4330 ° c (10.8 MPa).So before it melts, the solid carbon sublimes directly into the gas phase.

Not only is there no metal in the material known to man that will not melt at 10,000 degrees, but even those alloys will not. The most heat-resistant material ever made is Ta4HfC5, which has a melting point of 4,215 ℃. It is made of hafnium carbide and tantalum carbide, which have a higher melting point than tungsten (melting point is nearly 4,000 degrees).
