Abstract
Provided are a dielectric composition and a ceramic electronic component including the same. The dielectric composition includes (a) barium titanate having a specific surface area of 2.5 m2/g to 6.0 m2/g; (b) a mixture containing at least one or more materials selected from the group consisting of any one oxide of Mg, Ca, Sr, Ba and Zr, and any one carbonate thereof; (c) oxide containing at least one or more materials selected from the group consisting of Sc, Y, La, Ac, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu; (d) oxide containing at least one or more material selected from the group consisting of Cr, Mn, Fe, Co, and Ni; (e) oxide containing at least one or more material selected from the group consisting of V, Nb, and Ta; and (f) oxide containing at least one or more material selected from the group consisting of Si and Al. The dielectric composition can satisfy X8R characteristic, can be sintered at a low temperature, and can obtain high reliability.
