Sintering behavior of triol sol-gel derived Nb-doped PZT ceramics: Effects on phase, microstructure and electrical properties

The ceramicswere fabricated from nano-sizedNb-doped PZT powder, whichwas synthesized by a triol sol-gel method. The powder was pressed and sintered at the temperature in between 900-1250°C for 2-6 h with heating/cooling rates of 5-20°C min-1. The XRD results showed that increasing the sintering temp...
