Abstract

Sintering of PZT at high temperatures results in loss of Pb unless an ambient Pb activity is maintained. The tell-tale sign of Pb loss is an increased conductivity, usually manifested in unacceptably high values of tan δ. The conductivity is caused by oxygen vacancies and/or electron holes which are a by-product of Pb evaporation.
