Dielectric ceramic composition and multilayer ceramic capacitor including the same

摘要

A dielectric ceramic composition may include a base material main ingredient and an accessory ingredient. The accessory ingredient contains one or more selected from a group consisting of oxides and carbonates of one or more elements among Bi, Li, and Cu. When the accessory ingredient contains Bi, a content of Bi may be 0.1 to 1.0 part by mole, based on 100 parts by mole of the base material main ingredient, when the accessory ingredient contains Li, a content of Li may be 0.1 to 1.0 part by mole, based on 100 parts by mole of the base material main ingredient, and when the accessory ingredient contains Cu, a content of Cu may be 0.1 to 1.0 part by mole, based on 100 parts by mole of the base material main ingredient.

1. A dielectric ceramic composition comprising a base material main ingredient and an accessory ingredient,
wherein the accessory ingredient contains one or more selected from a group consisting of oxides and carbonates of one or more elements among Bi and Li, and when the accessory ingredient contains Bi, a content of Bi is 0.1 to 0.5 part by mole, based on 100 parts by mole of the base material main ingredient, and when the accessory ingredient contains Li, a content of Li is 0.1 to 0.5 part by mole, based on 100 parts by mole of the base material main ingredient, wherein the accessory ingredient further comprises a first accessory ingredient containing one or more selected from a group consisting of oxides and carbonates of one or more variable-valence acceptor elements among Mn, V, Cr, Fe, Ni, Co, Cu, and Zn, a sum of contents of one or more variable-valence acceptor elements among Mn, V, Cr, Fe, Ni, Co, Cu, and Zn contained in the first accessory ingredient being 0.1 to 2.0 parts by mole, based on 100 parts by mole of the base material main ingredient.
