Lead zirconate titanate is an oxide solid solution commonly written . Its perovskite structure can support switchable electric polarization and a strong piezoelectricity response.
Changing the zirconium-to-titanium ratio changes the competing crystal structures and the response to an applied field or stress. Composition, domain configuration, and processing therefore matter when using the material as a transducer.

Lead zirconate titanate (PZT) is a ceramic compound composed of lead, zirconium, and titanium. It has the chemical formula \( \text{Pb(Zr}_{x}\text{Ti}_{1-x})\text{O}_3 \), where \( x \) can vary to create different compositions of the material. PZT is well-known for its piezoelectric properties, which means it can generate an electrical charge in response to applied mechanical stress and vice versa.
