Hf1 B12
semiconductor· Hf1 B12
Hf1B12 is a hafnium boride ceramic compound belonging to the ultra-high-temperature ceramics (UHTC) family, characterized by an extremely high melting point and exceptional hardness. This material is primarily of research and development interest for aerospace and defense applications requiring extreme thermal protection, such as hypersonic vehicle leading edges, rocket nozzles, and reentry heat shields, where its stability at temperatures exceeding 2000°C makes it a candidate alternative to conventional refractories and carbon-based composites.
