· PbTaO3

PbTaO3 is a lead tantalate ceramic compound belonging to the perovskite family of ferroelectric and piezoelectric materials. It is primarily investigated in research and specialized applications requiring high dielectric constant, ferroelectric switching, or piezoelectric response, particularly in high-temperature environments where conventional ferroelectrics become unstable. Although not yet widely adopted in mainstream commercial applications compared to alternatives like PZT (lead zirconate titanate), PbTaO3 offers potential advantages in aerospace, medical ultrasound, and extreme-environment sensing due to its thermal stability and electromechanical properties.

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.
