· Sb4 Ta5

Sb4Ta5 is an intermetallic compound combining antimony and tantalum, belonging to the family of refractory metal-based semiconductors. This material is primarily studied in research and advanced materials development contexts for potential use in high-temperature electronics and specialized semiconductor applications where conventional silicon-based devices become unstable. The tantalum-antimony system is notable for its potential to operate in extreme thermal and chemical environments, though practical industrial adoption remains limited compared to established semiconductor platforms.
