Title:
DIELECTRIC CERAMIC COMPOSITION AND CERAMIC ELECTRONIC COMPONENT
Document Type and Number:
WIPO Patent Application WO/2019/198419
Kind Code:
A1
Abstract:
This dielectric ceramic composition comprises a first ingredient and a second ingredient. The first ingredient comprises 0.00 to 35.85% by mole of an oxide of Ca, 0.00 to 47.12% by mole of an oxide of Sr, 0.00 to 51.22% by mole of an oxide of Ba, 0.00 to 17.36% by mole of an oxide of Ti, 0.00 to 17.36% by mole of an oxide of Zr, 0.00 to 2.60% by mole of an oxide of Sn, 0.00 to 35.32% by mole of an oxide of Nb, 0.00 to 35.32% by mole of an oxide of Ta, and 0.00 to 2.65% by mole of an oxide of V. As the second ingredient, this dielectric ceramic composition comprises at least: 0.005 to 3.500% by mass of an oxide of Mn (a); and an oxide of Cu and/or an oxide of Ru (b). According to the present invention, a dielectric ceramic composition can be provided, wherein the insulation resistance value is high, changes in the electrostatic capacity are small even under a high-temperature environment, and dielectric losses at 25°C and 200°C are small.
