中文摘要 | 本實驗藉由添加氧化物ZnO來促進燒結緻密性,同時也改善 (Zr0.6Sn0.4)TiO�痕熒L波性質,如介電常數、品質因子(Q)、共振頻率溫度係數(τ f)。實驗結果顯示氧化物CaCO�偭鬘i降低共振頻率溫度係數,但卻大大降低品質 因子,是其最大缺點。(ZrxSnyZnz)TiO�瓷Ax+y+z=1的實驗結果顯示介電常數不因 Zn取代Zr或Sn而有太大變化,而τf的變化則受Zn取代Sn的影響較大,而 (Zr0.6Sr0.4xZnx)TiO�硃篘蝯痕G顯示,τf值因Zn量增加而下降,當x=0.2時,τ f=2.3ppm/℃。而介電常數隨Zn量而稍有下降,其值約為36以上。 |
英文摘要 | In this experiment, the densification of (Zr0.6 Sn0.4)TiO�� ceramic could be enhanced by the addition of ZnO oxide. Its microwave properties such as dielectric constant (k), quality factor (Q), and temperature coefficient of resonant frequency (τ f) could also be improved. Adding CaCO�� oxide lowers the τf value, but decreases quality factor Q seriously. In (Zrx Sny ZnzTiO��, where x+y+z=1, the results indicated that dielectric constant doesn't change much with there placement of Zr or Sn by Zn and the change of τf is related to the amount of Zn. For the (Zr0.6 Sn0.4-xZnx)TiO�� ceramics, the results revealed that with increasing Zn amount, τf decreases and the dielectric constant only slightly reduces, but is still kept at a value of above 36, when x=0.2, the τf value was 2.3ppm/℃. |
