Abstract
Soft agglomerate, fine particle size and amorphous PLZT powders are prepared from nitrates solutions. The effects of postprecipitation processing (washing, drying, raw powder aging and calcining temperature) on powder characteristics and on final densification are examined. Solid state reactions occur above 500°C and both PLZT and PbO phase appear on XRD-profiles. The Crystalline states of these PLZT and PbO are subjected on the above processing. A two-stage sintering is made with various processed powders. The application of acetone washed-aged raw powder and of calcination below 700°C is promissing to obtain fine PLZT ceramics.Keywords
