Tb4 Re4 B16

Tb₄Re₄B₁₆ is an experimental rare-earth transition-metal boride ceramic compound combining terbium, rhenium, and boron. This material belongs to the family of high-refractory boride ceramics being investigated for extreme-temperature and wear-resistant applications where conventional ceramics reach performance limits. Such materials are primarily of research interest rather than established industrial production, with potential applications in aerospace thermal protection, cutting tools, and high-temperature structural components where their combination of refractory nature and potential hardening from rhenium addition could provide advantages over single-phase alternatives.
