- W2247205462 abstract "本实验研究了(1- x )(Mg 0.7 Zn 0.3 )TiO 3 – x (Ca 0.61 La 0.26 )TiO 3 (MZT-CLT)系陶瓷的微观结构和微波介电性能, 通过(Ca 0.61 La 0.26 )TiO 3 来协调(Mg 0.7 Zn 0.3 )TiO 3 陶 瓷 的谐振频率温度系数. MZT-CLT陶瓷的主晶相为(Mg 0.7 Zn 0.3 )TiO 3 , 第二相为Ca 0.61 La 0.26 TiO 3 和(Mg 0.7 Zn 0.3 )Ti 2 O 5 . 烧结温度和陶瓷组成对微波介电性能影响显著, 当烧结温度为 1275℃ 时, 可以获得良好的致密度, 当烧结温度超过 1300℃ 时, Zn的蒸发导致陶瓷致密度和介电性能下降. 随着(Ca 0.61 La 0.26 )TiO 3 含量的增大, 材料的介电常数增大, 品质因数减小. 当 x =0.13, 烧结温度为 1275℃ 保温4h, (MZT-CLT)陶瓷具有优良微波介电性能, e r =26, Q·f =86000 GHz, τ f = -6×10 - 6 /℃." @default.
