DIELECTRIC CERAMIC COMPOSITION, DIELECTRIC MATERIAL AND MULTILAYER CERAMIC CAPACITOR INCLUDING THE SAME

摘要

There is provided a dielectric ceramic composition including: a major component (a barium titanate-based base material); and a minor component, wherein in an XRD analysis of a sintered body obtained by sintering the dielectric ceramic composition, when a (110) peak of BaTiO3 is set as 1.00, a ratio of a peak of pyrochlore (RE2Ti2O7) at about 30.5 degrees with respect to the (110) peak of BaTiO3 satisfies 0.02 or less, where RE is at least one of Y, Dy, Ho, Sm, Gd, Er, La, Ce, Nd, Tb, and Pr.

1. A dielectric ceramic composition comprising:
a major component (a barium titanate-based base material); and a minor component, wherein the dielectric ceramic composition is sintered to form a sintered body, and in an XRD analysis of the sintered body, when a (110) peak of BaTiO3 is set as 1.00, a ratio of a peak of pyrochlore (RE2Ti2O7) at about 30.5 degrees with respect to the (110) peak of BaTiO3 satisfies 0.02 or less, where RE is at least one of Y, Dy, Ho, Sm, Gd, Er, La, Ce, Nd, Tb, and Pr, and the minor component includes: a fifth minor component including at least one selected from the group consisting of oxides and carbonates of at least one of Ba and Ca; and a sixth minor component including at least one selected from the group consisting of oxides and carbonates of Si, and glass including Si, and when a total content of the at least one of Ba and Ca included in the fifth minor component is x and a content of Si included in the sixth minor component is y, x/y satisfies 1.44 to 2.56.
