Titanate microwave dielectric ceramic and preparation method thereof
The invention relates to a titanate microwave dielectric ceramic and a preparation method thereof, in particular to a microwave dielectric ceramic material (0.85-x)MgTiO<3>-xMg<2.05>SiO<4.05>-0.15Ca<0.61>Nd<0.26>TiO<3> (x=0.25, 0.35, 0.45 and 0.55) with a low dielectric constant and a high quality factor and a preparation method thereof, and belongs to the technical field of microwave dielectric ceramics. The preparation method comprises the following nine steps: burdening, mixing, drying, pre-sintering, ball-milling, re-drying, granulating, degumming and sintering. The dielectric constant [epsilon]r of the obtained titanate microwave dielectric ceramic is 9.74-17.82, the quality factor Q*f is 36992-63899 GHz, the preparation process is simple, the process is pollution-free, the production cost is relatively low, the microwave dielectric property of the titanate microwave dielectric ceramic can be remarkably improved, and wide application prospects are realized.
