摘要：
A method for making a raw dielectric ceramic powder having a composition represented by the general formula ABO 3 includes the steps of allowing a carbonate powder of the element A to adsorb an organic polymer compound to produce an organic carbonate powder containing the adsorbed organic polymer compound, mixing the organic carbonate powder and an oxide powder of the element B to prepare a mixed powder, and calcining the mixed powder. Also disclosed are a dielectric ceramic produced by molding and firing the raw dielectric ceramic powder produced by the method and a monolithic ceramic capacitor fabricated using the dielectric ceramic.
