Abstract: A dielectric ceramic composition is provided to satisfy high permittivity, low dielectric loss, and low-temperature sintering characteristics of a dielectric substance containing Ba6Ti2Nb8O30 as a main component. A method for preparing a dielectric ceramic composition includes the steps of: calcining a base composition of Ba6Ti2Nb8O30; adding a sintering aid selected from the group consisting of ZnO-B2O3-based glass having a composition of ZnB2O4 or Zn3B2O6, an oxide mixture selected from a mixture of B2O3 and CuO and a mixture B2O3 and ZnO, and mixtures thereof, to the calcined base composition, and then mixing the admixture; grinding the mixture and molding the ground mixture into a predetermined shape; and sintering the molded material at 1000 ‹C or below.
