Hafnium Carbide is primarily used in ultra-high-temperature environments, such as thermal protection systems for hypersonic vehicles and rocket propulsion components. Its exceptional hardness and wear resistance make it suitable for cutting tools and abrasion-resistant coatings. In nuclear reactors, HfC serves as a neutron absorber due to its high thermal neutron capture cross-section. Researchers also explore its potential in semiconductor and electronic applications where extreme durability is required.
