Abstract
The invention relates to a method for manufacturing dielectric ceramic powder and a multilayer ceramic capacitor using the ceramic powder. According to the invention, BaCOpowder is dispersed into a solution of solvent and dispersant to prepare BaCOslurry and then the resultant BaCOslurry is wet-milled. Also, TiOpowder slurry is mixed into the wet-milled BaCOslurry to form mixed slurry and then the mixed slurry is dried into mixed powder. Finally, the dried mixed powder is calcined to produce BaTiOpowder.
