Effect of sintering and milling time on lead magnesium niobate nanocrystallite phase

The perovskite phase is seen to increase when the sintered temperature is increased; suggesting the heat energy required for the perovskite phase is less in these samples compared to the sample sintered for low temperature. Also the perovskite phase increase with the increasing of sintering time up to 6 h and then decrease. The perovskite phase increased with increased milling time.
