Abstract
For sodium niobate (NaNbO3) ceramics containing in the nonpoled state about 30% of the ferroelectric Q phase, the temperature dependences of the dielectric constant ε and pyroelectric coefficient p are studied. The results obtained show that the transition from the Q phase into the high‐temperature nonpolar phase seems to be a diffuse one and the remanent polarization remains nonzero up to ≈370 °C, i.e., well above the temperature of the p(T) maximum (≈270 °C). Poled NaNbO3 ceramics possess high figures of merit for pyroelectric sensors and NaNbO3‐based materials are prospective for application in the noncooled infrared detectors.
