· TbP

Terbium phosphide (TbP) is a rare-earth ceramic compound belonging to the monopnictide family, characterized by a rock-salt crystal structure and strong ionic-covalent bonding. This material is primarily explored in research and specialized semiconductor applications where its unique electronic and thermal properties offer advantages in high-temperature and high-pressure environments. TbP is notable for its potential in thermoelectric devices, optical systems requiring rare-earth functionality, and as a model compound for studying lanthanide physics, though it remains less commercially established than more common ceramics used in structural applications.
