Product Description
Product Introduction
Lead Zirconate Titanate (PZT) powder, also known as Lead Zirconium Titanate, is a widely used piezoelectric and dielectric ceramic material with a perovskite structure. Engineered for advanced electronic applications, PZT powder combines lead zirconate (PbZrO₃) and lead titanate (PbTiO₃) in various ratios to achieve superior ferroelectric, piezoelectric, and dielectric performance.
Our PZT powder is specially developed for use in ceramic capacitors, particularly multilayer ceramic capacitors (MLCCs), and other precision electronic components such as transducers, actuators, and ultrasonic devices. With a tightly controlled particle size distribution and high purity, it supports optimal sintering behavior and stable electrical properties.
This material offers a high dielectric constant, strong electromechanical coupling, and excellent thermal and frequency stability, making it ideal for devices that require reliable performance under varying environmental conditions. The PZT powder is compatible with a variety of shaping methods, including dry pressing, tape casting, and screen printing, making it versatile for both bulk and thin-film ceramic component production.

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.
