· ThSi2

Thorium silicide (ThSi2) is an intermetallic ceramic compound belonging to the silicide family, characterized by a hexagonal crystal structure and metallic bonding characteristics that bridge traditional ceramics and metals. It is primarily investigated for high-temperature structural applications where exceptional thermal stability and oxidation resistance are critical, with development focus in aerospace, nuclear, and advanced energy sectors. ThSi2 is notable for maintaining strength at elevated temperatures better than many conventional ceramics, making it a candidate material for next-generation turbine engines and nuclear fuel cladding, though it remains largely in research and development phases rather than widespread industrial production.
