采用高温固相反应制备了Na+ β″ 氧化铝 ,利用熔盐离子交换法进行Ag+交换形成Ag+ β″ 氧化铝 ,并研究了其热稳定性 .X射线衍射和扫描电镜分析中发现 ,在5 0 0℃以上有分解现象且随温度升高更加明显 .通过电化学方法研究其分解行为并讨论了其分解机制
The Na + β “alumina was prepared by high temperature solid-state reaction and the Ag + β” alumina was exchanged by molten salt ion exchange method to form Ag + β "alumina.The thermal stability was also studied.It was found by X-ray diffraction and scanning electron microscope The decomposition phenomenon is more obvious at 0 ℃ and the temperature is more obvious.The decomposition behavior is studied by electrochemical method and its decomposition mechanism is discussed
