Abstract
Official abstract text for this publication.
A manufacturing method of a dielectric ceramic composition includes attaching a reactive functional group to a surface of a base material powder particle of a perovskite structure.
First claim
Opening claim text (preview).
What is claimed is: 1. A dielectric ceramic composition, comprising: a base material powder particle of a perovskite structure; and a diffusion type additive, wherein a concentration peak layer of the diffusion type additive is present at a depth of 0.8 nm to 8.5 nm from a surface of the base material powder particle, and wherein the diffusion type additive comprises a first subcomponent including one or more selected from a group consisting of Y, Dy, Ho, Er, Gd, Ce, Nd, Sm, Tb, Tm, La, Gd, Yb, oxides thereof, and carbonates thereof, and wherein an average particle diameter (D50) of the dielectric ceramic composition is in a range of 100 nm to 500 nm. 2. The dielectric ceramic composition of claim 1 , wherein the diffusion type additive comprises three or more of a second subcomponent including one or more selected from a group consisting of Mg, Li, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Zr, Ru, Rh, Pd, Ag, Cd, In, Sn, Sb, Ta, W, Pb, Bi, V, Nb, B, oxides thereof, and carbonates thereof.
