摘要
本文对TiO_2陶瓷晶界层电容器进行了较为系统的研究。用液相喷雾干燥法制备含Nb^(5+),Ba^(2+)微量杂质的TiO_2超细原料粉末,研究了TiO_2陶瓷的电性能与烧结温度和测试条件的关系,阐述了TiO_2晶界层电容器的形成机制。
A systematic study of TiO2 ceramic boundary layer capacitor (BLC) ismade. TiO2 ultrafine powder microdoped with Nb5+, Ba2+ is prepared by spray drying. The relations between the dielectric properties of TiO2 and the sintering temperature, measuring conditions are studied. The mechanism of TiO2 ceramic BLC is illustrated.
