Abstract

Lead, zirconium and titanium were coprecipitated from their aqueous salt solutions using oxalic acid. The precipitate on heating to 850°C gave phase pure PZT powder which showed good sinterability. The average grain size in the pellets sintered at 900°C for 6 h was about 1 μm. Barium and strontium were found to coprecipitate with lead facilitating partial substitution. Barium modified samples showed a lowering of the Curie temperature from 355 to 230°C while strontium modified samples showed a lowering from 355 to 245°C for 15 mol% substitution.
