CaCu3Ti4O12具有很高及對溫度變化率低(100-400K)的介電常數,此性質極符合電子元件的實際應用規格如X5R。但是造成其高介電的主要機構為何,目前仍然沒有定論。晶域的存在對於單晶以及多晶CaCu3Ti4O12的介電行為提供了一個合理的解釋,而本研究藉由添加CaSiO3並探討其對CaCu3Ti4O12的影響,嘗試得到更多關於晶域存在的證據。
CaCu3Ti4O12 which exhibits a large dielectric constant and the dielectric constant is weakly varying in the temperature range 100~400K. The mechanism for inducing the huge dielectric response of CaCu3Ti4O12 still remains unresolved. The existence of domains provides a reasonable explanation for dielectric behavior of single crystal and polycrystal CaCu3Ti4O12. In order to find more evidences about existence of domains, we try to discuss effects of CaSiO3-doped CaCu3Ti4O12 in this research.
