Fast Mechanochemical Synthesis of Nano-structured PMN at Low Temperature
Source abstract
Abstract
Nanoscale lead magnesium niobate(PMN) powders of perovskite phase were synthesized by the screw grinder for 3h starting from raw materials of oxides.The influences of reaction conditions on products,such as weight of raw materials,grind power and grind time,were studied in detail.The results show that high grind power can reduce the synthesis time,improve the purity of products and decrease the particle size.The mechanochemical mechanism of PMN synthesis is confirmed via cross reaction experiments between raw materials.Magnesium niobate is firstly formed through mechanochemical reaction between MgO and Nb2O5,then reacted with PbO to get the PMN finally.
