Effects of Microwave Sintering on the Properties of (Mg0.9Zn0.1)TiO3-(Ca0.61La0.26)TiO3 Ceramics
摘要
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/℃.关键词
