TbSi2 is a terbium disilicide ceramic compound belonging to the metal silicide family, characterized by a hexagonal crystal structure and moderate stiffness. This material is primarily investigated in research contexts for high-temperature structural applications, particularly in aerospace and nuclear environments where its thermal stability and oxidation resistance at elevated temperatures are beneficial. TbSi2 represents part of the rare-earth silicide family that shows promise as a candidate for ultra-high-temperature ceramic matrix composites (CMCs) and thermal barrier coatings, offering potential advantages over conventional alumina-based ceramics in extreme operating conditions, though widespread industrial adoption remains limited compared to established alternatives like SiC or Y2O3.
