· PmPaO3

PmPaO3 is a rare-earth perovskite oxide ceramic composed of promethium and protactinium in a perovskite crystal structure. This is a research-phase compound studied primarily for its potential in high-temperature structural applications and nuclear fuel matrix materials, given the nuclear properties of its constituent elements. The material remains largely experimental and is not widely commercialized; its development is driven by specialized nuclear and advanced materials research rather than general engineering practice.

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.
