摘要
使用柠檬酸盐法成功制备出分散良好的颗粒状BNT系纳米粉体。经TEM和XRD分析,粉体的平均粒径约30 nm,其主晶相为Nd2Ti2O7,经1 300℃烧结成瓷后还出现了BaNd2Ti4O12相。此类材料具有良好的高频特性,用此类材料研制出的单片微波陶瓷电容器具有良好的微波特性。
In present paper, the homogeneous dispersion nano powder of BaO-Nd2O3-TiO2 was prepared by citrate method. The average size of particle is about 30nm by X-ray diffraction and Transmission Electron Microscope. Its main phase is Nd2Ti2O7, and there is a little second phase of BaNd2Ti4O12 after 1300℃ sintering. The single layer microwave ceramic capacitor prepared by this ceramic material which has excellent microwave dielectric properties.
