Product Description
Product Introduction
Lead Zirconate Titanate (PZT) is a highly versatile and widely used electric ceramic material known for its exceptional piezoelectric, ferroelectric, and dielectric properties. As a member of the perovskite family, PZT ceramics combine the properties of lead zirconate (PbZrO₃) and lead titanate (PbTiO₃) to deliver a tunable material system used extensively in sensors, actuators, capacitors, and ultrasonic devices.
The material exhibits strong electromechanical coupling, thermal stability, and reliability across a broad temperature range, making it suitable for industrial, medical, automotive, and consumer electronics applications. The powder can be processed using conventional ceramic fabrication techniques such as pressing, tape casting, and screen printing, enabling flexible manufacturing options.

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.
