Method for Preparing Dielectric Material Composition for Multi Layer Ceramic Condenser and the Dielectric Material Composition Having Improved Dispersibility therefrom

摘要

The present invention has an improved ceramic dielectric composition prepared dispersion method for a multilayer ceramic capacitor and thus relates to a composition for a dielectric capacitor, ; in the multilayer ceramic capacitor manufacturing method for the dielectric composition, MgOR, MnOR, BaOR and alkoxide of CaOR, and YOR, DyOR, from the group consisting of HoOR and ErOR alkoxide (wherein the selected at least one kinds, R is -CH ₃ , -CH ₂ CH ₃ , -CH ₂ CH ₂ CH ₃ or -CH ₂ CH ₂ CH ₂ CH ₃ an alkyl group), a conductive metal powder is added while maintaining the pH 4.0-8.0 in sol dissolved metal powder mixture, and then heat-treated to prepare a dielectric composition characterized in that the metal powder to the sol gel there is provided a method for producing a dielectric composition for a multilayer ceramic capacitor as set. The method also provides a dielectric composition for a multilayer ceramic capacitor having improved dispersibility prepared by. ; The method of the present invention to improve the dispersibility of the dielectric composition by using the additive of the alkoxide form of the dielectric properties and can have excellent electrical characteristics and reliability are improved manufacturing a multilayer ceramic capacitor.
