本文利用拉曼散射、X光繞射和延伸X光吸收譜等光學方法來測量A(B’1/3B”2/3)O3鈣鈦礦陶瓷中氧八面體結構、 1：2有序結構與其微波性質的關連性。樣品共有三組，第一組樣品為不同燒結條件的Ba(Mg1/3Ta2/3)O3。此組樣品皆為Q×f值非常高的樣品，X光繞射分析發現1：2有序程度高其Q×f值越高。此組Ba(Mg1/3Ta2/3)O3樣品的微觀結構非常相近，氧八面體體積差異無法由拉曼散射和X光吸收實驗解析。第二組樣品為鎳掺雜之Ba(Mg1/3Ta2/3)O3，即xBa(Ni1/3Ta2/3)O3 +(1-x)Ba(Mg1/3Ta2/3)O3 (x=0~0.03)。X光吸收譜可以很明確知道鎳原子是取代鎂原子的晶格位置，而當鎳掺雜濃度越多時，氧八面體越緊密，此時介電常數也隨之減小；且鎳掺雜的越多，1：2有序結構被破壞的程度愈高，Q×f值也隨之降低。第三組樣品是燒結溫度介於1350~1550oC的五個Ba(Co1/3Nb2/3)O3陶瓷樣品。當燒結溫度為1400oC時，實驗發現Ba(Co1/3Nb2/3)O3具有最小的介電常數和最大的Q×f值。此樣品的氧八面體也最緊密、1：2有序程度也最好。燒結溫度高於1400oC之樣品，介電常數開始變大、Q×f值變小，且氧八面體結構開始鬆散、1：2有序程度變差。實驗顯示燒結條件會強烈的影響到晶體內氧八面體結構與1：2有序程度，其微波特性與氧八面體微觀結構直接相關。
