PZT (Lead Zirconate Titanate) is a piezoelectric ceramic material with a crystalline, perovskite structure that exhibits high sensitivity and temperature resistance. It is widely used for applications that require precise motion control, such as sensors, actuators, transducers, and ultrasonic devices. In this article, we will explain what PZT is, how it works, and where you can buy it.

PZT is a compound of lead, zirconium, titanium, and oxygen with the general formula Pb [Zr x Ti 1-x ]O 3 , where x can vary from 0 to 1. Depending on the value of x, PZT can have different properties and applications. For example, when x is close to 0, PZT has a high dielectric constant and is suitable for capacitors. When x is close to 0.5, PZT has a high piezoelectric coefficient and is suitable for actuators. When x is close to 1, PZT has a high electromechanical coupling factor and is suitable for transducers.

PZT belongs to a class of materials called ferroelectrics, which have spontaneous electric polarization that can be reversed by an external electric field. This means that PZT can generate electric charges when subjected to mechanical stress (the direct piezoelectric effect) or change its shape when subjected to an electric field (the converse piezoelectric effect). These effects make PZT ideal for converting mechanical energy into electrical energy or vice versa.

PZT has a perovskite crystal structure, which consists of a cubic unit cell with a central metal atom (zirconium or titanium) surrounded by oxygen atoms at the corners and a lead atom at the center of each face. The central metal atom can shift slightly from its equilibrium position due to thermal fluctuations or external forces, creating an electric dipole moment. When an electric field is applied across the thickness of a PZT sheet, the central metal atoms align with the field direction, causing the sheet to expand or contract along the polarization axis and contract or expand perpendicular to it. The amount of deformation depends on the strength of the electric field and the piezoelectric coefficient of the material.

Conversely, when a mechanical force is applied to a PZT sheet, the central metal atoms are displaced from their equilibrium positions, creating an electric charge on the opposite surfaces of the sheet. The amount of charge depends on the magnitude of the force and the piezoelectric coefficient of the material.
