Ultra-wide-temperature stable sodium bismuth titanate-based dielectric ceramic material and preparation method thereof
The invention discloses an ultra-wide-temperature stable sodium bismuth titanate-based dielectric ceramic material and a preparation method thereof, the chemical formula of the ultra-wide-temperature stable sodium bismuth titanate-based dielectric ceramic material is (1-x) (0.94 Bi0. 5Na0. 5TiO3-0.06 BaTiO3)-xCa (Fe0. 5Ta0. 5) O3, and x ranges from 0.18 to 0.22. The invention also discloses a preparation method of the ultra-wide-temperature stable sodium bismuth titanate-based dielectric ceramic material. The sodium bismuth titanate-based dielectric ceramic material is prepared by a traditional solid phase method, and has excellent dielectric properties and temperature stability: the room temperature dielectric constant at 1kHz is 670, the dielectric loss is as low as 0.0037, the change rate of the dielectric constant in the temperature range of-150 to 450 DEG C is less than 15%, and the dielectric loss in the temperature range of-110 to 300 DEG C is less than 0.02. The ultra-wide-temperature stable sodium bismuth titanate-based dielectric ceramic material provided by the invention is suitable for being used in ceramic dielectric capacitors in high and low temperature extreme environments.
