· JVASP-37421· Th3B

Th₃B is a thorium boride ceramic compound belonging to the rare-earth and actinide boride family, characterized by high density and ceramic bonding. This material is primarily of research and specialized industrial interest, where its extreme hardness, refractory properties, and thermal stability make it relevant for high-temperature structural applications and nuclear fuel matrix materials. Thorium borides are investigated as alternatives to conventional ceramics in demanding environments where resistance to thermal shock, chemical corrosion, and radiation damage is critical.
