- Borides and carbides of hafnium, zirconium, tantalum and related composites combine outstanding levels of robustness and refractoriness and are currently widely recognized as the unique materials for harsh service environments, especially for aerospace, rocket propulsion and energy applications. Additional applications that take significant advantages from the characteristics of UHTC include refractory linings and furnace heating elements, high temperature electrodes, substrates for microelectronics and cutting tools to name a few. Hafnium carbide is also an excellent candidate as an high-temperature solar absorber and conductor because of its melting point above 3300°C and has an intrinsic spectral selectivity. HfC and ZrC can be considered for thermionic/thermoelectric converters at high temperatures, exploiting proper tuning of the grain boundary or secondary phases, or modifying carrier concentration and mobility (literal)
