| Summary: | Fine powders of neodymium substituted-bismuth titanate, Bi4-xNdxTi3O12(BNT) with x ranging from 0 to
1.0 were prepared by the fue1-free combustion process at 1ow combustion temperature of about 200oC The
influence of Nd addition on the bismuth titanate system (BIT) was studied and characterized by the
methods of XRD, Rietveld method and SEM. It was found that the intermediate phase of Bi12TiO20 had
reduced with addition of Nd. Crystallinity and orthorhombicity of the system was found to be decreased as the Nd content increases. The size of platey grains is strongly influenced by the Nd added to the system.
