Rare earth ion modified filter ceramic for 5G base station, and preparation method thereof
The invention relates to a preparation method of a rare earth ion modified filter ceramic for a 5G base station, wherein the chemical formula of the rare earth ion modified filter ceramic is 0.6CaTiO3-0.4ZnTaNb2O6, a rare earth oxide and lithium oxide combined multi-element sintering aid xRe2O3+yLi2O is added, x is larger than 1 and smaller than 2 wt%, y is larger than 1 and smaller than 3 wt%, and Re is one of Y, Eu, Dy, La and Pr. According to the preparation method, a ceramic matrix is modified, so that a high Q*f of 80000-90000 GHz, stable dielectric constant epsilon r of 21-23 and tau f of -2-0 ppm/DEG C close to zero are obtained, and the ceramic is applicable to filter ceramics for 5G base stations.
