Influence of atmospheric annealing on the conductivity of Mn-doped PZT ceramics

Research output: Chapter in Book/Report/Conference proceeding › Chapter

Abstract

Conductivity measurements were carried out on Mn-doped PZT ceramics in order to investigate the changes in defect chemistry with annealing, by identifying the charge carriers such as lead or oxygen vacancies. PZT compositions were prepared by sol-gel method in rhombohedral region Pb(Zr 0.56 Ti0.44)O3 with Mn contents 0.4, 0.8, 1.5 and 2 wt.%. Nano-sized powder (∼21nm) was obtained after calcination and bulk density values of > 98% were achieved upon sintering. It was found that nitrogen annealing reduced the electrical conductivity strongly as compared to oxygen and air annealing and the possible charge carriers were single ionised oxygen vacancies VO• along with VO •• and Vpb∥ vacancies.
