Preparation and Grain Growth of Pb(Zr0.95Ti0.05)O3 Porous Ceramics Prepared by One-Step Pyrolysis Process Using Non-Aqueous Pechini Method

摘要：

　　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 ℃ 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.
