摘要

This study examines the dielectric properties and total harmonic distortion of lead zirconate ceramics sintered at varying temperatures using PbO and ZrO2 nanopowders with particle sizes of 500 nm and 20 nm, respectively. The use of nanoscale powders resulted in a decrease in sintering temperature in comparison to conventional ceramics fabricated from 1 μm particles. The highest dielectric permittivity was observed in samples sintered at 1100°C. A decrease in permittivity was recorded at sintering temperatures exceeding 1200°C. However, cooling within the 226 – 208°C range induced the formation of a ferroelectric phase.
