Abstract: PURPOSE: Provided is a PbO-ZrO2-CaO-TiO2 system dielectric ceramic composition with high dielectric constant(more than 100) for microwave products of small size and light weight such as filters, duplexer and resonators. CONSTITUTION: The microwave dielectric ceramic composition is represented by the formula, (1-y)(Pb1-xCaxZr0.9Ti0.1)O3 + ySrZrO3 (0.3
