· JVASP-24787· ThB2O5

ThB2O5 is a ceramic compound in the thorium borate family, combining thorium oxide with boric oxide in a mixed-oxide structure. This material is primarily of research and specialized high-temperature interest rather than a common engineering ceramic, with potential applications in nuclear technology, refractory systems, and advanced ceramics where thorium-containing phases offer neutron absorption or thermal stability benefits. Engineers would consider this compound in niche applications requiring radiation shielding or extreme thermal environments, though its use is limited by regulatory constraints on thorium-bearing materials and the availability of well-established alternatives for most conventional ceramic applications.
