· JVASP-40385· TbBS3

TbBS3 (terbium borosulfide) is a rare-earth ceramic compound combining terbium with boron and sulfur elements, representing an emerging material in the borochalcogenide family. While primarily a research-phase compound, materials in this class are investigated for applications requiring high mechanical stiffness, thermal stability, and potential optical or electronic functionality in extreme environments. TbBS3 would appeal to engineers exploring alternative ceramics for high-temperature structural applications, radiation-resistant components, or specialized optical systems where rare-earth dopants provide functional benefits.
