What metal is more resistant to tungsten than tungsten? Do you have a material with a melting point of 10,000 degrees?
Of all the metallic elements of the periodic table, tungsten has the highest melting point, with a melting point of 3422 ℃ (boiling point is 5930 ℃), and no metal element has a higher melting point than tungsten. The reason the melting point of tungsten is very high is related to the metal bond whose bond energy is very high. Tungsten is element 74, located in the sixth cycle of the VIB family in the periodic table. Among the congeners of tungsten, they have the largest number of valence electrons in metal elements, up to six, which means that each atom can form six metal bonds, so the bond energy of this group of elements is extremely high, resulting in a very high melting point. Combined with other bonding parameters, tungsten has the strongest bonding ability, which makes tungsten the metal with the highest melting point. However, there are other ingredients that can withstand higher temperatures than tungsten, and solid carbon can withstand temperatures of 3627 ℃. But the carbon has no fixed melting point (1 standard atmospheric pressure) because it sublimates at about 3627 ℃, and the three-phase temperature of carbon is 4330 ℃ (pressure is 10.8 MPa). As a result, solid carbon sublimates directly into a gaseous state before it melts. Among the known materials, not only does no metal melt at 10,000 degrees, but not even those alloys. So far, the most heat-resistant material made by humans is Ta4HfC5, which has a melting point of 4215 ℃. It is made of hafnium carbide and tantalum carbide (melting point nearly 4000 degrees), which is higher than the melting point of tungsten. In addition, it should be noted that the melting point of the material is related to the pressure, and the higher the pressure, the higher the melting point. But when the temperature and pressure are greater than the critical value, the material will become superfluid, which has lost the meaning of melting point.
