Publication number: US20220028620A1
Application number: 17/498,872

Abstract:
A multilayer ceramic capacitor that includes a ceramic body including a stack of a plurality of dielectric layers and a plurality of first and second internal electrodes; and first and second external electrodes provided at each of both end faces of the ceramic body. Each of the plurality of dielectric layers contain Ba, Ti, P and Si. The plurality of dielectric layers include an outer dielectric layer located on an outermost side in the stacking direction; an inner dielectric layer located between the first and second internal electrodes; and a side margin portion in a region where the first and second internal electrodes do not exist. In at least one of the outer dielectric layer, the inner dielectric layer and the side margin portion, the P and the Si segregate in at least one of grain-boundary triple points of three ceramic particles.

Publication number: US20220028614A1
Application number: 17/498,430

Abstract:
A dielectric ceramic composition that contains an oxide of A, R, and B and an oxide of Mn. The A is at least one selected from the group consisting of K and Na. The R is at least one selected from the group consisting of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y, and Sc. The B is at least one selected from the group consisting of Nb and Ta. The molar ratio of the A:R:B:Mn is 2−x:1+x/3:5+y:z. The x, y, and z satisfy −0.3≤x≤0.6, −0.5≤y≤0.5, and 0.001≤z≤0.5, respectively.
