· PmNbO3

PmNbO3 is a perovskite ceramic compound combining promethium (Pm) and niobium (Nb) oxides; this is an experimental research material rather than a production ceramic. The promethium-based perovskite family is investigated for potential applications in functional ceramics and solid-state devices where ferroelectric, piezoelectric, or dielectric properties are required, though practical use remains limited due to promethium's radioactivity and scarcity. Engineers would consider this compound primarily in advanced research contexts exploring novel perovskite chemistries and phase stability, rather than as a mainstream engineering material for conventional applications.

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.
