| 摘 要： | 采用传统固相反应法制备了(1-x)(Mg0.7Zn0.3)TiO3-x(Ca0.61La0.26)TiO3(MZCLT)微波介质陶瓷。分析了(Ca0.61La0.26)TiO3掺杂量对MZCLT陶瓷相结构、烧结性能和介电性能的影响。所制MZCLT陶瓷的主晶相为(Mg0.7Zn0.3)TiO3和(Ca0.61La0.26)TiO3,还存在微量的(Mg0.7Zn0.3)Ti2O5。当x=0.13,1275℃烧结4h时,0.87(Mg0.7Zn0.3)TiO3-0.13(Ca0.61La0.26)TiO3陶瓷介电性能较佳:εr=26.7,Q·f=86011GHz(8GHz),τf为-6×10-6/℃,优于(Mg0.7Zn0.3)TiO3陶瓷介电性能(εr=19.2,Q·f=253000GHz,τf为-39×10-6/℃)。

| Abstract: | (1-x)(Mg0.7Zn0.3)TiO3-x(Ca0.61La0.26)TiO3(MZCLT) system microwave dielectric ceramics were prepared by conventional solid state route.The effects of(Ca0.61La0.26)TiO3 doped amount on the phase composition,sintering characteristics and dielectric properties of MZCLT ceramics were investigated.The prepared MZCLT ceramics show mixed phases of(Mg0.7Zn0.3)TiO3 and(Ca0.61La0.26)TiO3 as the main phases in association with some minor phase(Mg0.7Zn0.3)Ti2O5.For x=0.13,the MZCLT ceramics exhibit excellent microwave d... |
