Glowing zircon carbide heating rod at 2000 °C.

Ultra-high temperature ceramics have unique properties such as extremely high melting temperatures (> 3000 ° C) as well as high hardness, chemical stability and strength even at high temperatures. This makes them potential candidates in a variety of high temperature structural applications such as engines, high-speed vehicles, plasma technology, innovative nuclear fuels, thermal barriers and diverters, cutting tools, furnace elements and high-temperature shielding. UHTC materials include carbides, nitrides and borides of transition metals, including compounds of the subgroup IV (Ti, Zr, Hf) plus TaC.
