DIELECTRIC CERAMIC, METHOD FOR MANUFACTURING SAME, AND DIELECTRIC RESONATOR

摘要

A dielectric sintered body of the present invention contains Ba, Nb, and at least one of Zn and Co, as main components, and K and Ta as subcomponents. The ratio A of the peak intensity p2 of the (111) plane peak to the peak intensity p1 of the (310) plane peak in an X-ray diffraction measurement is 0.9 to 1.5. The half bandwidth C of the (111) plane peak ranges from 0.12 to 0.22°. The d-value D of the (111) plane peak ranges from 2.363 to 2.371. The dielectric sintered body has a Perovskite structure.
