摘要: 应用微波方法合成了固相反应难于制备的Na5YSi4O12纯相,讨论了微波合成条件对产物的影响。与溶胶-凝胶法相比,微波法反应速率快,选择性强,合成的样品具有特异的聚集态、缺陷和微结构,从而导致离子导电活化能下降。

Abstract: Single phase Na5YSi4O12 which is difficult to be prepared by conventional solid state reaction, was synthesized by microwave radiation synthesis method.The relationship between synthesis conditions and the phases in products was discussed.Acomparison was made of the properties of samples prepared by Sol-Gel method with those by microwave radiation synthesis method,respectively.Compared to conventional Sol-Gel method, the experimental procedure was much simplified and reaction time was shrtened when Na5YSi4O12 was prepared by microwave radiation synthesis method.The sample prepared by microwave method has a particular micro-structure,aggregating state and defect structures, which leads to the decrease of ionic conducting activation energy.
