摘要
通过微波烧结和常规烧结法成功制备(1-x)(Mg0.9Zn0.1)TiO3-x(Ca0.61La0.26)TiO3(x=0.15,简称85M9Z1CLT)陶瓷.实验结果表明,微波烧结大大缩短了85M9Z1CLT陶瓷的烧结周期,抑制了杂质相(Mg0.9Zn0.1)Ti2O5的生成;微波烧结制备的85M9Z1CLT陶瓷表现出Zn蒸发量少、晶粒更均匀、颗粒更细小的微观结构.与传统烧结相比,微波烧结的85M9Z1CLT陶瓷的品质因数提高了21％.在1325℃下微波烧结20 min升降温速率为15℃/min时,85M9Z1CLT微波介电陶瓷的性能最佳:εr=25.63,Q·f=116000 GHz,τf=+1×10-6/℃.
Abstract
(1-x)(Mg0.9Zn0.1)TiO3-x(Ca0.61La0.26)TiO3 (x=0.15,referred to as 85M9Z1CLT) system ceramics were prepared by microwave sintering and conventional sintering.The experimental results demonstrated that the sintering cycle of 85M9Z1CLT ceramics was greatly shortened and the impurity phase (Mg0.9Zn0.1)Ti2O5 was eliminated by microwave sintering.Moreover,the 85M9Z1CLT ceramics prepared by microwave sintering show more uniform,fine-grained microstructure as well as much less Zn evaporation.As a result,the quality factor was increased by 21％ compared with conventional sintering.All samples were sintered at 1325 ℃ for 20min with heating and cooling rate of 15 ℃/min and gave excellent microwave dielectric properties:εr=25.63,Q·f=116,000 GHz,τf=+1×10-6/℃.
