· TaSi2

Tantalum silicide (TaSi₂) is a refractory ceramic compound combining tantalum and silicon, belonging to the family of transition metal silicides. It is valued in high-temperature applications for its thermal stability, oxidation resistance, and electrical conductivity—properties that set it apart from conventional oxides and make it useful in extreme environments where maintaining mechanical integrity at elevated temperatures is critical.
