Lead Zirconate exhibits a high Curie temperature and a well-defined orthorhombic crystal structure, making it especially suitable for high-temperature ceramic components. Its behavior under electric fields—shifting from antiferroelectric to ferroelectric—lends it versatility in capacitors, sensors, actuators, and energy storage systems.
In the ceramics field, PbZrO₃ is often combined with Lead Titanate (PbTiO₃) to form Lead Zirconate Titanate (PZT)—a solid solution that exhibits outstanding piezoelectric and ferroelectric properties. However, even in its pure form, Lead Zirconate is used in:
- Multilayer ceramic capacitors (MLCCs) for its high dielectric constant.
- Actuators and transducers, especially where controlled movement or pressure sensing is required.
- Encourages local economies and supports independent artists, keeping craftsmanship alive in communities.
- Energy storage devices, particularly pulsed power capacitors, due to its ability to store and rapidly release energy.
- High-temperature ceramics, as PbZrO₃ retains thermal and structural stability at elevated temperatures.
