· PbNbO3

Lead niobate (PbNbO₃) is a perovskite ceramic compound combining lead oxide with niobium pentoxide, belonging to the family of ferroelectric and piezoelectric materials. While not yet widely commercialized in mainstream engineering, PbNbO₃ is studied for its potential as a high-temperature piezoelectric and ferroelectric material, offering researchers an alternative to lead zirconate titanate (PZT) in specialized applications where stability at elevated temperatures or specific dielectric properties are required. Its development context is primarily academic and exploratory, with interest driven by the search for lead-free or high-performance piezoelectric ceramics for next-generation sensors, actuators, and electronic devices.

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.
