可低溫燒結之介電-磁性陶瓷系統

Low-Fire Processing and Properties of Ferrite + Dielectric Ceramic Composite

指導教授 : 簡朝和

摘要


本研究探討三種介電材料與磁性材料Ni-Cu-Zn鐵氧磁體在不同比例下混合共燒之燒結緻密行為、結晶相組成、介電性及磁性。BZN和PNZT系統在900℃持溫2小時的燒結條件下,可分別得到大於95%和90%之相對燒結密度。當BZN與Ni-Cu-Zn鐵氧磁體混合共燒時,BZN中的Bi元素會往Ni-Cu-Zn鐵氧磁體的方向擴散,使得BZN與Ni-Cu-Zn鐵氧磁體間的燒結相容性提高,讓此系統容易燒結緻密。同時在結晶相組成方面,由於Bi往Ni-Cu-Zn鐵氧磁體的方向擴散,因此BZN的結晶相會由Bi2(Zn1/3Nb2/3)2O7轉變為Bi1.5ZnNb1.5O7。在介電性質方面,因為Bi1.5ZnNb1.5O7的出現,使得介電常數因此提高。電感特性方面,BZN在系統中所佔的比例愈高,材料的自我共振頻率愈高,使得此材料系統可以應用在更高頻率的範圍之下。
