摘　　要：以二氧化硅,三氧化二铝,氧化钙和氧化镁为主要原料,分别采用微波辐射和传统电加热制备了一系列CaOMgO-Al_2O_3-SiO_2(CMAS)系微晶玻璃材料,对比两种方法的热处理制度对微晶玻璃结构与性能的影响,并进一步讨论了微波非热效应的影响。利用DTA、XRD、SEM和综合力学性能仪等手段,研究了两种对该系微晶玻璃显微结构及性能的影响。实验结果表明,两种方法制备的微晶玻璃主晶相均为辉石相,力学性能也基本相当。与传统热处理方法相比,微波法可在更短时间内制备出性能较好的微晶玻璃材料,微波非热效应有助于降低其晶化温度。A series of CaO-MgO-Al2O3-SiO2 （ CMAS） glass ceramics were prepared by microwave radiation and conventional electrical heating with silica, three alumina, calcium oxide and Magnesium Oxide as the main raw materials. The effect of two different heating treatments on the structure and properties of the glass ceramics was compared, and the effect of non-thermal effect of microwave was further discussed. Besides, the influence of two methods on micro structure and properties of the glass ceramics was studied by means of DTA, XRD, SEM and the Mechanical Property Comprehensive Testing Machine. The experimental results showed that the main crystalline phases of the glass ceramics prepared by the two methods are all pyroxene phase, and the mechanical properties are basically similar. Compared with the traditional heating treatment method, microwave method can prepare glass ceramics with good properties in less time. Non-thermal effect of microwave is helpful to decrease the crystallization temperature of the sample.
