PURPOSE:To obtain raw material powder for dielectric porcelain composition by uniformly supporting and fixing an addition element compound to the surface of individual particles of a base composition. CONSTITUTION:In producing raw material powder for barium titanate-based dielectric porcelain composition by blending barium titanate as a base composition with an addition element, barium titanate powder and powder comprising at least one addition element composed of an inorganic acid salt are blended in an organic solvent containing ethylene carbonate, slurried and the slurry is dried and heat-treated. |
