Abstract
Dielectric ceramic compositions for microwave application which are expressed as (1-x)ZnNb,O,- xTiO,and designed with mole fractions of TiO,(x=0.2 to 0.8). CuO of 0.5 to 12.0 % by weight of the total weight of the compositions is added to the compositions. At least one additive oxide of 0.05 to 5.0% by weight of the total weight among V,O,, Sb,O,, Bi,O,, B,O,, NiO, WO,, AgNO,, ZnO, and MgO is added to the compositions. They have good sintering and dielectric characteristics and made through simple manufacturing processes, and lower the production costs.
