Tio2 Nanopowder

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.
