Preparation and Grain Growth of Pb(Zr_0.95Ti_0.05)O₃ Porous Ceramics Prepared by One-Step Pyrolysis Process Using Non-Aqueous Pechini Method

Abstract:

Pb(Zr0.95Ti0.05)O3 powders were prepared by one-step pyrolysis process from non-aqueous Pechini method. Porous Pb(Zr0.95Ti0.05)O3 ceramics were obtained by sintering the chemically prepared powders and the grain growth in the porous ceramics was investigated. For the powders calcined at 450 °C for 10 h by one-step pyrolysis process, the grain growth exponent value was observed to be 3.3 while the apparent activation energy was 193 kJ/mol.
