· JVASP-37524· TbAs3

TbAs₃ is a rare-earth arsenide ceramic compound composed of terbium and arsenic, belonging to the family of refractory intermetallic ceramics. This material is primarily of academic and specialized research interest rather than widespread industrial use, with potential applications in high-temperature semiconductors, optoelectronic devices, and advanced thermal management systems where rare-earth compounds offer unique electronic or magnetic properties. Engineers would consider TbAs₃ for niche applications requiring the combined thermal stability and electronic properties of rare-earth arsenides, though commercial availability and processing complexity typically limit its use to research environments or specialized defense/aerospace programs.
