Beschreibung
Zusammenfassung:	The invention relates to a method for manufacturing dielectric ceramic powder and a multilayer ceramic capacitor using the ceramic powder. According to a first aspect of the invention, BaCO 3 powder is dispersed into a solution of solvent and dispersant to prepare BaCO 3 slurry and then the resultant BaCO 3 slurry is wet-milled. Also, TiO 2 powder slurry is mixed into the wet-milled BaCO 3 slurry to form mixed slurry and then the mixed slurry is dried into mixed powder. Finally, the dried mixed powder is calcined to produce BaTiO 3 powder. In a second aspect of the invention CaCO 3 powder slurry and TiO 2 powder slurry are mixed into the wet milled BaCO 3 slurry, to form mixed slurry. Then the mixed slurry is dried and calcinated to produce BaCaTiO 3 powder.
