Abstract :
Pb(Zr0.95Ti0.05)O3 powders were prepared by one-step pyrolysis process from 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 3.55 while the apparent activation energy was 78.75 kJ/mol.
