在微波介電陶瓷材料中,BaO-Ln2O3-TiO2 (Ln=La、Pr、Nd、Sm及Gd)系列因有較高介電常數與高品質因子,並可藉由摻雜離子來改善共振頻率溫度係數,故非常適合使用在微波頻率的通訊用途上。
在本論文研究中,選擇使用BaO-Nd2O3-xTiO2微波介電陶瓷掺雜不同含量鉍離子,形成Ba(Nd1-yBiy)2TixO2x+4的各種化學劑量比(x = 4~5,y = 0~0.2)以進行降低燒結溫度及降低共振頻率溫度係數的探討與研究。
研究發現掺雜鉍離子能造成液相燒結之功能,使Ba(Nd1-yBiy)2TixO2x+4於1350oC熔化達到降低熔點之目的,並會使晶粒尺寸增加使得介電常數上升 ; 而所形成含鉍的相能夠有效降低共振頻率溫度係數,但是須控制好所掺雜鉍離子的濃度,以避免共振頻率溫度係數為負值及過低的品質因子。
於1300oC燒結x = 4.7、y = 0.15的化學劑量比時,有優良的介電性質,其介電常數(εr )為86.379、品質因子(Q×f )為5206.089 GHz、共振頻率溫度係數(τf )為0。
