ceramic

· JVASP-24554· K5ThF9

K5ThF9 is a thorium fluoride-based ceramic compound, part of the rare-earth and actinide fluoride ceramic family. These materials are primarily investigated for specialized applications requiring high thermal stability, chemical inertness, and radiation resistance, particularly in nuclear fuel forms and high-temperature containment systems where conventional ceramics are unsuitable.
