Effect of TiO2 Nanopowders on the Sintering and Electric Properties of Lead Zirconate Titanate Ceramics
XRD, SEM, bulk density and dielectric properties measurements were used to investigate the effect of TiO2 nanopowder substitution for conventional TiO2 micro-powder on the sintering and electric properties of PZT ceramics. Results revealed that the sintering temperature of dense Pb(Zr0.53Ti0.47)O3 ceramics was lowered about 50°C ~ 100°C when 20% and 40% of conventional TiO2 micro-powder was substituted by TiO2 nanopowder. The electric properties were kept or even enhanced in the PZT ceramics adopted the TiO2 nanopowder.
