PRIMARY PARTICLE COATED BY COLORING COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide an improved technology for preparing a colored ceramic molding by a RP process particularly.

SOLUTION: Primary particles of oxide-ceramic materials have an average particle size in the range from 10 to 1,000 nm and are treated in a suspension including coloring components. More specifically, the primary particles of the oxide-ceramic materials have an average particle size in the range from 10 to 1,000 nm and are coated with the coloring components.
