Title:
DIELECTRIC CERAMIC COMPOSITION, DIELECTRIC DEVICE AND METHODS FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2015/119112
Kind Code:
A1
Abstract:
A dielectric ceramic composition (10) provided with: a dielectric particle section (22) which is a compound containing a metal element other than Ba or Ti in some of the BaTiO3; and a particle boundary section (24) containing ZnO and present between the particles of the dielectric particle section (22). This dielectric ceramic composition may be obtained, for example, by forming and sintering a powder preparation containing a dielectric-particle-section starting material which is a compound containing a metal element other than Ba or Ti in some of the BaTiO3, and a particle-boundary-section starting material containing ZnO.
