· JVASP-91571· TbHO2

TbHO2 is a rare-earth oxide ceramic compound combining terbium and holmium elements in a fluorite-type crystal structure. This material belongs to the family of rare-earth oxides investigated for high-temperature applications, nuclear fuel matrices, and advanced ceramics requiring exceptional thermal and mechanical stability. While primarily a research compound rather than a commercial commodity, TbHO2 represents the broader potential of mixed rare-earth oxides for extreme-environment engineering where thermal conductivity control, radiation resistance, and chemical inertness are critical design drivers.
