N2 - Microwave sintering of Pb(Zr, Ti)O3, PZT, based ceramics was investigated using multimode heating at 2.45 GHz and 30 GHz and compared to conventional thermal processing. For both PZT-5 and PZT-5H "soft" piezoelectric ceramics, microwave processing resulted in a reduction of sintering temperature by more than 150 K. Of significance to the production of high surface area lead-based components, minimal PbO volatility was detected for samples processed as high as 1200°C. In contrast to conventionally processed PZTs, minimal grain size dependency of the dielectric and piezoelectric properties was observed.
