Product Description
Product Introduction
Lead Zirconate (PbZrO₃) powder is a specialized dielectric ceramic material widely used in the electronics industry for its excellent ferroelectric, piezoelectric, and dielectric properties. As a key component in the perovskite ceramic family, lead zirconate is especially important in the manufacture of multilayer ceramic capacitors (MLCCs), piezoelectric devices, thermistors, and actuators.
Our Lead Zirconate powder is manufactured through precise solid-state synthesis techniques, resulting in highly pure, fine, and uniform particles. With controlled stoichiometry and phase stability, this material ensures reliable performance across a wide range of dielectric applications. PbZrO₃ is often used in combination with lead titanate (PbTiO₃) to form PZT (lead zirconate titanate) materials, which are extensively used in transducers, sensors, and piezoelectric ceramics.
Lead zirconate is also valued for its anti-ferroelectric behavior, making it a strong candidate for energy storage and high-voltage capacitor applications. It offers high dielectric constants, low dielectric loss, and stable temperature characteristics, which are critical for advanced electronic systems.

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.
