  • Multi-layer ceramic electronic component having external electrode with base film and electrically conductive thin film
    Patent number: 11024461
    Abstract: A multi-layer ceramic electronic component includes: a ceramic body including a main surface facing in a first direction, an end surface facing in a second direction orthogonal to the first direction, a side surface facing in a third direction orthogonal to the first and second directions, and internal electrodes laminated in the first direction; and an external electrode formed on a surface of the ceramic body, the external electrode including a base film including an end-surface-covering portion that covers the end surface, and a main-surface-covering portion that covers part of the main surface continuously from the end-surface-covering portion, an electrically conductive thin film including a base-covering portion that covers the main-surface-covering portion, and a ceramic-body-covering portion that extends from the base-covering portion in the second direction and covers part of the main surface, and a plating film that covers the electrically conductive thin film and the base film.
    Type: Grant

  • Recycled ceramic slurry, recycled ceramic powder, ceramic electronic part, and fabricating methods therefor
    Patent number: 7148170
    Abstract: Recycled ceramic slurry is produced by a method including the steps: dissolving the waste material of unfired ceramic in a solvent to form a waste solution; and adjusting a composition of the waste solution to thereby produce the recycled ceramic slurry. If the waste material of unfired ceramic includes a metal component, the metal component may be removed therefrom before the step of adjusting the composition of the waste solution.
