CePO4
ceramic· JVASP-35139· CePO4
Cerium phosphate (CePO4) is an inorganic ceramic compound belonging to the rare-earth phosphate family, characterized by high density and rigid crystal structure. It is primarily investigated for nuclear waste immobilization and thermal/radiation-resistant applications, where its chemical durability and ability to accommodate actinide elements make it an attractive alternative to conventional borosilicate glasses in the nuclear fuel cycle. CePO4 is also explored as a ceramic matrix phase in composite systems and for high-temperature structural applications where chemical inertness and phase stability are critical.

Regulatory Screening
Environmental
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
