· Th4 P8 O28

Th4P8O28 is a thorium phosphate ceramic compound belonging to the family of actinide-bearing phosphate ceramics. This material is primarily investigated in nuclear waste immobilization research, where thorium phosphate ceramics are explored as durable host phases for encapsulating radioactive and hazardous elements. The thorium phosphate ceramic family is notable for its chemical durability and resistance to aqueous leaching, making it a candidate alternative to traditional borosilicate glass for long-term geological storage of nuclear waste.
