Abstract
The results of this study are summarized as follows:<br>(1) High density tetragonal PZT ceramics with compositions of {Pb(ZrxTi1-x)O3+0.5mass% MnO2}, where x=0.10-0.50, were successfully synthesized by hot isostatic pressing.<br>(2) HIPed samples with x=0.20 had the highest bulk density of 7.82g/cm3, which is 98.2% of the theoretical density.<br>(3) The Curie temperature TC for PZT ceramics with x=0.10-0.50 decreased linearly with an increase in Zr content. The rate of linear decrease m calculated from the linear plot of TC with x was approximately 3.0°C/mol% Zr.<br>(4) The PZT sample with x=0.20 exhibited the highest figure of merit F.M. of around 2.1×10-11C·cm/J. Assuming that the volume specific heat Cv of the present sample with x=0.20 and that of PZTZBM ceramic with x=0.30 are the same (3.1J/cm3·K), the F.M. for voltage responsivity of pyroelectric IR sensors fabricated using these ceramics which have the same tetragonal structure should be nearly equal.
