Ion modified titanium dioxide ceramic material with high dielectric constant and preparation method thereof
The invention relates to an ion modified titanium dioxide ceramic material with a high dielectric constant and a preparation method thereof, and belongs to the field of environment-friendly dielectric ceramics. The ceramic material disclosed by the invention is as shown in a general formula as follows: (A0.5Nb0.5)xTi(1-x)O2, wherein A is Bi, Al, Ga, Y, Sc, Yb, Dy, Sm, Gd and Pr, and x is not smaller than 0.005 mol content and not larger than 0.150 mol content. The ceramic material is prepared by adopting a traditional solid phase sintering process; the raw materials in the general formula are added with different trivalent A elements and the same pentavalent Nb element; the obtained ceramic material is as high as 10<6> in dielectric constant and as low as 6% in dielectric loss. The ceramic prepared by the method disclosed by the invention has a relatively large practical value in the present age when electronic elements are miniaturized and lightened, and especially the elements prepared from the ceramic have practical application values in various electronic elements such as capacitors and dynamic storage.
