Abstract
There is provided a multilayer ceramic electronic component including: a ceramic body in which internal electrodes and dielectric layers containing a barium titanate-based compound containing calcium (Ca) are alternately stacked; and external electrodes disposed on outer surfaces of the ceramic body and electrically connected to the internal electrodes. The dielectric layer includes interfacial portions adjacent to the internal electrodes and a central portion disposed between the interfacial portions, the interfacial portion having a calcium (Ca) concentration higher than that of the central portion.

A multilayer ceramic electronic component comprising:
- a ceramic body in which dielectric layers containing a barium titanate-based compound containing calcium (Ca) and internal electrodes are alternately stacked;
- and
- external electrodes disposed on outer surfaces of the ceramic body and electrically connected to the internal electrodes,
- wherein the dielectric layer includes interfacial portions adjacent to the internal electrodes and central portions disposed between the interfacial portions, the interfacial portions having a calcium (Ca) concentration higher than a calcium concentration of the central portions.
A method of manufacturing a multilayer ceramic electronic component, the method comprising:
- preparing ceramic green sheets containing barium titanate-based powder;
- applying an internal electrode paste containing a ceramic additive containing calcium to the ceramic green sheets;
- stacking the ceramic green sheets to which the internal electrode paste is applied;
- and
- sintering the stacked ceramic green sheets to form a ceramic body including internal electrodes and dielectric layers,
- wherein the dielectric layers include interfacial portions adjacent to the internal electrodes and central portions disposed between the interfacial portions, the interfacial portions having a calcium (Ca) concentration higher than a calcium concentration of the central portions.
