Abstract
A method for manufacturing a powdered raw material of a basic powdered dielectric ceramic composition having compounds containing metal elements thereon. The method comprises the steps of dispersing a basic powdered dielectric ceramic composition in water to form a slurry, adding a silicon compound to the slurry to coat the powder, adding a solution containing the metal elements and a precipitating agent reactive therewith to form a precipitate, while the slurry is being stirred, and rinsing and drying the slurry.
