本研究是利用X-光繞射分析研究 (1 - x)Ca(Mg1/3Nb2/3)O3-(x)CaZrO3 (CMN-CZ) (x = 0 ~ 0.50) 固溶體系統的結構並量測其燒結體之微波介電性質，進而探討本系統在 1500℃/8 h 之成分、結構與微波介電性質的關係。隨著 x 的增加，本系統之晶體結構中 B-site 之陽離子的排列從 1:2 有序 (x = 0) 轉變成 1:1 有序 (x = 0.10) 與 disordered (x = 0.50)。此有序結構相轉換與各陽離子之氧八面體之比率的變化有關。1:2 有序程度主導 x = 0 ~ 0.10 之 Qxf 值隨著 x 的增加而降低的趨勢。扭曲的 [NbO6] 八面體之比率主導本系統之相對介電係數隨著 x 的增加而昇高以及 x = 0.10 ~ 0.50之共振頻率溫度係數隨著 x 的增加而往正的方向變動的趨勢。

The structures of compositions in the (1 - x)Ca(Mg1/3Nb2/3)O3-(x)CaZrO3 (CMN-CZ) (x = 0 ~ 0.50) solid solution system have been examined using X-ray diffractometry, and their microwave dielectric properties have been characterized in the microwave range. The composition-structure-property relationships of this system sintered with 1500℃/8 h were reported. As x was increased, the transition of B-site cation ordered perovskites from 1:2 (x = 0) to 1:1 (x = 0.1) and disordered (x = 0.5) types was observed and related to the variation in the proportion of cation-oxygen octahedra. A decrease in Qf value (x = 0 ~ 0.10) with increasing x was dominated by a decrease in the degree of 1:2 order. A increase in relative dielectric constant (x = 0 ~ 0.50) and the positively change of temperature coefficient of resonance frequency (x = 0.10 ~ 0.50) with increasing x were dominated by a decrease in the proportion of [NbO6] octahedra.
