Effect of niobate B-site precursors on phase formation and particle size of lead nickel niobate powders
A perovskite phase of Pb(Ni1/3Nb2/3)O3or PNN powders has been synthesized by a rapid vibro-milling technique. Both NiNb2O6and Ni4Nb2O9have been employed as nickel niobate precursors, with the formation of the PNN phase investigated as a function of calcination conditions by DTA and XRD techniques. M...

| Summary: | A perovskite phase of Pb(Ni1/3Nb2/3)O3or PNN powders has been synthesized by a rapid vibro-milling technique. Both NiNb2O6and Ni4Nb2O9have been employed as nickel niobate precursors, with the formation of the PNN phase investigated as a function of calcination conditions by DTA and XRD techniques. Morphology and phase composition have been determined via a combination of SEM and EDX techniques. The nickel niobate precursor and calcination condition have been found to have a pronounced effect on the phase and morphology evolution of the calcined PNN powders. It is seen that optimization of calcination conditions can lead to a single-phase PNN in both methods. However, the formation temperature for single-phase PNN powders was lower for the synthetic method employing a NiNb2O6precursor. © 2007 Elsevier B.V. All rights reserved. |
