· JVASP-45372· Tb2S3

Tb2S3 is a rare-earth sulfide ceramic compound composed of terbium and sulfur, belonging to the family of lanthanide chalcogenides. This material is primarily of research and development interest rather than a mature commercial product, investigated for its potential in high-temperature structural applications, optoelectronic devices, and specialized solid-state chemistry. The rare-earth sulfide family is explored for thermal stability, refractory properties, and potential use in niche aerospace and materials science applications where conventional ceramics may be insufficient.
