摘要 利用固相法合成Sr（Zn1/3 Nb2／3）O3（SZN）微波介质陶瓷，分别在1400℃，1450℃与1500℃下进行烧结，通过X射线衍射（XRD）、扫描电子显微镜（SEM）和拉曼光谱法系统的研究了烧结温度对SZN微波介质陶瓷微观结构的影响．研究发现烧结温度对SZN微波介质陶瓷微观结构有重要影响，较高的烧结温度有利于晶相发育完全，并可以获得较大的晶粒尺寸，同时还可以获得较高的阳离子有序度． The Sr（Zn1/3 Nb2/3）O3（SZN） microwave dielectric ceramics were synthesized by the conventional solid - state sintering technique at 1 400℃ , 1 450℃ and 1 500℃. X - ray diffraction （XRD） , Scanning electron microscope （SEM） and Raman spectroscopy were employed to evaluate the effect of sintering temperature on the microstructure of the SZN microwave dielectric ceramics. The results show that sintering temperature impacts not only the mierostrueture but also the dielectric property. The higher sintering temperature is conducive to fully develop the crystal phase, and can obtain large grain size. Meanwhile, higher sintering temperature can also obtain a higher degree of cationic ordering.
