  • Patent number: 10395828
    Abstract: The dielectric layers are formed from a dielectric porcelain formed from crystal particles containing barium titanate as a main component and containing a rare earth element, and the crystal particles have, in a particle boundary vicinity, a low concentration region in which the concentration of the rare earth element is lower than the concentration of the rare earth element in an inside. The crystal particles further contain vanadium, and the low concentration region contains a larger amount of the vanadium than the amount of the vanadium in the inside. The crystal particles further contain magnesium and manganese, and the magnesium and the manganese have a concentration gradient that is at a maximum at the particle boundary vicinity and that lowers toward the inside.
    Type: Grant
    Filed: October 26, 2016
    Date of Patent: August 27, 2019
    Assignee: KYOCERA Corporation

  • Patent number: 9972441
    Abstract: Resolution means: The multilayer ceramic capacitor includes an effective dielectric portion and cover layers. The effective dielectric portion includes dielectric ceramic layers and internal electrode layers that are alternately stacked. The cover layers are made of ceramic material and disposed on top and bottom surfaces of the effective dielectric portion. The cover layers include ceramic particles, which constitute the majority of the cover layers, and include glass particles. Some of the glass particles are present in gaps, which are formed between the ceramic particles.

  • Publication number: 20170323727
    Abstract: Object: A layered ceramic capacitor having an increased breakdown voltage is provided. Resolution means: The layered ceramic capacitor includes an effective dielectric portion (9) and cover layers (11). The effective dielectric portion (9) includes dielectric ceramic layers (5) and internal electrode layers (7) that are alternately stacked. The cover layers (11) are made of ceramic material and disposed on top and bottom surfaces of the effective dielectric portion (9). The cover layers (11) include ceramic particles (13), which constitute the majority of the cover layers, and include glass particles (15). Some of the glass particles (15) are present in gaps (17), which are formed between the ceramic particles (13).
