Product Applications

Lead Titanate (PbTiO₃) is a perovskite-type ferroelectric material , strong spontaneous polarization, and tetragonal crystal structure at room temperature. These properties make it highly valuable in a variety of advanced electronic and electromechanical applications. PbTiO₃ is widely used in the production of PTC Thermistors, piezoelectric transducers, ultrasonic sensors, sonar systems, and surface acoustic wave (SAW) devices. Its ferroelectric properties also make it an ideal candidate for non-volatile ferroelectric memory (FeRAM), as it allows for data storage through reversible polarization states.

In the electro-optic field, PbTiO₃ is employed in tunable filters and modulators, particularly in devices where high-temperature stability and fast response times are required. Additionally, due to its high dielectric constant and thermal stability, PbTiO₃ is used in the manufacturing of high-temperature ceramic capacitors. In scientific research, PbTiO₃ serves as a model material for studying phase transitions, domain structures, and the fundamental behavior of ferroelectric and piezoelectric systems. It is also commonly used in composite systems for the development of multiferroic and smart materials.

 

FAQ

Q1: Can Lead Titanate be used directly in piezoelectric devices?

A: Yes, but it typically requires processing into dense ceramic or thin-film form and undergoing poling (electric field treatment) to align domains for optimal piezoelectric performance.

Q2: What are the safety considerations when handling PbTiO₃?

A: PbTiO₃ contains lead, which is toxic if inhaled or ingested. Proper safety precautions should be taken, including the use of gloves, masks, and working under a fume hood or in a well-ventilated area.

Q3: Is customization available for PbTiO₃ materials?

A: Absolutely. We offer PbTiO₃ in various particle sizes (including nano-scale), purity levels, and packaging formats. Custom formulations and material processing (e.g., pellet pressing, sintering) can also be arranged based on application requirements.
