· JVASP-35098· TbTe2

TbTe2 is an intermetallic ceramic compound composed of terbium and tellurium, belonging to the rare-earth chalcogenide family of materials. This is primarily a research-phase material studied for its electronic and thermal transport properties rather than a conventional engineering ceramic. The material is of interest in thermoelectric device development and solid-state physics applications where rare-earth tellurides offer tunable band structures and potential for energy conversion at elevated temperatures.
