摘要：用传统固相反应法制备了复杂钙钛矿结构陶瓷(Ca_(1-x)Sr_(x))_(1.35)Sm_(0.65)Al_(0.65)Ti_(0.35)O_(4)(x=0.4,0.3,0.2,0.1),用XRD表征其结构,SEM表征微观形貌,并测试样品的微波介电性能。随着Sr含量的增加其介电常数从19.8增加到24.1,温漂从-07ppm/℃增大到30.1ppm/℃,Q^(*)f值从65300GHz减少到36200GHz。当x=0.1时有较好的微波介电性能,介电常数为20.3,温漂为14.9ppm/℃,Q^(*)f值为65322GHz。表明复杂钙钛矿结构A2BO4的(Ca_(1-x)Sr_(x))_(1.35)Sm_(0.65)Al_(0.65)Ti_(0.35)O_(4)陶瓷是一种新型微波介电材料体系,具有很好的应用前景。
