· JVASP-21547· ThP2O7

Thorium pyrophosphate (ThP₂O₇) is a ceramic compound combining thorium oxide with pyrophosphate chemistry, belonging to the family of actinide-based phosphate ceramics. This material is primarily of research and specialized industrial interest rather than mainstream engineering use, with potential applications in nuclear waste immobilization, high-temperature ceramics, and radiation-resistant structural materials where thorium's nuclear properties and the chemical stability of phosphate frameworks offer advantages over conventional ceramics.
