Abstract
An improvd dielectric ceramic composition for high frequencies and a method for preparation of the same, capable of being advantageously used for a substrate of dielectric resonator, glabal positioning system and the like in high frequency regions, which consists of a main component of Zr.sub.1-X Sn.sub.X Ti.sub.1+Y O.sub.4 and sintering aid component of MnO.sub.2, NiO and Sb.sub.2 O.sub.3, wherein the molar ratio X and Y are respectively, 0.1.ltoreq.X.ltoreq.0.3 and -0.1.ltoreq.Y.ltoreq.0.1 and the sintering aid component essentially consists of, based on the total amount of the main component, 3% or less of MnO.sub.2 and 2 wt % or less of NiO and Sb.sub.2 O.sub.3 in a combined amount.
