TITLE OF THE INVENTION Dielectric ceramics ABSTRACT OF THE DISCLOSURE Dielectric ceramics having a composition expressible by (1 - w) (xBaO ? yNa2O ?zNb2O5) + wMeO ? ZrO2 wherein Me denotes Ca or Sr, 0.593 ? x ? 0.762, 0.04 ? y ? 0.13, 0.174 ? z ? 0.32, x + y + z = 1, and 0 < w ? 0.95. They exhibit large dielectric constant and low microwave loss with high temperature- stability for resonant frequency and are suitable for use in dielectric resonators, electrical filters, substrates, etc.
