Microwave dielectric ceramic material with high quality factor and high dielectric constant and preparation method thereof
The invention discloses a microwave dielectric ceramic material with high quality factor and high dielectric constant and a preparation method thereof, and belongs to the technical field of ceramics. The invention aims to solve the problem that the existing microwave dielectric ceramic is difficult to have high dielectric constant and high quality factor at the same time. The chemical general formula of the microwave dielectric ceramic material is SrTi1-x (A0. 5Ta0. 5) xO3, in which A is Cr or Al, 0 lt; x is smaller than or equal to 0.05; the preparation method comprises the following steps: 1, carrying out ball milling and sieving on raw materials, and finally calcining to obtain pre-sintered powder; 2, ball-milling and sieving the pre-sintered powder to obtain ball-milled powder; 3, adding a binder into the ball-milled powder, grinding and sieving to obtain granulated powder; and fourthly, the granulated powder is pressed into a blank, degummed and sintered. The invention is used for the microwave dielectric ceramic material with high quality factor and high dielectric constant and the preparation thereof.
