· Tb4 B16

Tb4B16 is a rare-earth boride ceramic compound combining terbium and boron in a defined stoichiometric ratio. This material belongs to the family of rare-earth hexaborides and similar boride ceramics, which are primarily of research and specialized industrial interest rather than commodity applications. The compound is investigated for high-temperature structural applications, thermionic emission devices, and advanced refractory systems where its rare-earth dopant provides unique electronic and thermal properties unavailable in simpler boride ceramics.
