A-5 Phase formation and morphology of PbZrO_3-Pb(Ni_(1/3)Nb_(2/3))O_3 powders via a columbite precursor synthetic route(Session: Ceramics I)

Abstract

Solid solution perovskite structure of lead zirconate-lead nickel niobate ceramics, (1-x)PbZrO_3-xPb(Ni_(1/3)Nb_(2/3))O_3 (PZ-PNN) with x=0-0.5, were synthesized via the columbite precursor method. The formation of the perovskite phase in the calcined powders has been investigated as a function of calcination conditions by TG-DTA and XRD techniques. The morphology evolution was determined by scanning electron microscopy (SEM) technique.
