摘要

CaCu3Ti4O12(CCTO)材料是一鈣鈦礦立方晶結構，可以在一定的溫度範圍內保持一巨大的介電常數。但是造成有如此巨大介電常數的原因，目前還沒有定論。由於CaCu3Ti4O12在不需要其他的添加物就能夠擁有這麼好的介電性質。本實驗將探討添加劑對於CaCu3Ti4O12的影響。實驗室以傳統陶瓷製程來製備CaCu3Ti4O12在加入MgO、MnO、ZnO作為添加劑。

The CaCu3Ti4O12 (CCTO)is a cubic perovskite structure. It has s a large dielectric constant which is independent of temperature. The mechanism for inducing the huge dielectric response of CaCu3Ti4O12 still remains unresolved. The CaCu3Ti4O12 with high dielectric constant does not need any additives.This thesis is syudy the effect oh additives on the properties of CaCu3Ti4O12 ceramic.The CaCu3Ti4O12 were additived included MgO、MnO、ZnO by traditional ceramic fabrication.
