· JVASP-35537· TbO3

Terbium oxide (TbO₃) is a rare-earth ceramic compound belonging to the lanthanide oxide family, notable for its high density and thermal stability. While primarily of research interest rather than high-volume production, it is investigated for specialized applications in optoelectronics, catalysis, and high-temperature structural materials where rare-earth oxides offer unique electronic or thermal properties unavailable from conventional ceramics.
