· PbTiO3

Lead titanate (PbTiO₃) is a ferroelectric ceramic compound belonging to the perovskite family, characterized by spontaneous electric polarization and strong piezoelectric coupling. It is primarily used in electromechanical transducers, sensors, and actuators where precise control of deformation or electrical response under stress is required; notable applications include ultrasonic devices, mechanical switches, and positioning systems. PbTiO₃ remains an important benchmark material in ferroelectric research and device development, though lead-free alternatives are increasingly preferred in new designs due to environmental and regulatory concerns.

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.
