Abstract

Sol-gel derived La₂Ti₂O₇ and Nd₂Ti₂O₇ exhibited preferential grain orientation on sintering. The extent of orientation is quantified in terms of the Lotgering orientation factor from the XRD intensities of pellets sintered at different temperatures. The microstructural studies indicated extensive orientation with sintering and also a change in morphology of the grains from acicular to large platelets.
