摘　　要：在氩气气氛下微波辐射加热Mg-TiO2混合物,通过XRD、SEM研究了不同n(Mg)/n(TiO2)和反应温度对产物物相、形貌的影响。n(Mg)/n(TiO2)影响产物中Mg-TiO2化合物的种类和亚氧化钛的生成,对产物的形貌没有明显影响。反应温度影响产物的物相比例,温度升高会导致产物的颗粒烧结粗大。使用微波加热Mg-TiO2虽然生成了钛酸镁及亚氧化钛,但生成量少、分离困难,因此该制备方法不可取。The Mg/TiO2 mixture was heated by microwave radiation in an argon atmosphere.The effects of different n(Mg)/n(TiO 2)and reaction temperatures were studied.The n(Mg)/n(TiO 2)affects the types of Mg-TiO2 compounds and the production of titanium dioxide in the product.It has no obvious effect on the morphology of the product.The reaction temperature affects the product comparative example.The increase of temperature will lead to the coarse sintering of the product particles.Although magnesium titanate and TinO2 n-1 are formed in the product,the microwave heating Mg-TiO 2 process is not suitable for preparing magnesium titanate and titanium dioxide due to the difficulty of separation and the small amount of formation.
