ceramic

· JVASP-20335· U3P4

U3P4 is a uranium phosphide ceramic compound belonging to the actinide phosphide family, used primarily in nuclear fuel and advanced reactor applications. Its high density and ceramic nature make it relevant for specialized nuclear engineering contexts where uranium-bearing ceramics serve as fuel forms or neutron moderators. While not a mainstream commercial material like UO2, U3P4 represents a research-level alternative fuel composition studied for its thermophysical properties in advanced nuclear systems.

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.
