Abstract: 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. -
