摘要

PROBLEM TO BE SOLVED: To provide a copper plated Al₂O₃ composite powder with which a sintered compact having excellent heat radiability and high density can be produced, to provide a method for producing the composite metal powder, to provide a copper plated Al₂O₃ composite powder sintered compact which has excellent heat radiability and high density, and to provide a method for producing the sintered compact.;SOLUTION: The copper plated Al₂O₃ composite powder is provided with a copper covered layer in which the content of copper is ≥60wt.% In the method for producing the copper plated Al₂O₃ composite powder, Al₂O₃ powder is preliminary subjected to pretreatment of imparting a catalyst by imidazolesilane and palladium chloride, thereafter, 1 to 10 wt.% copper is applied thereto by electroless plating, and next, copper is applied thereto by substitution plating.;COPYRIGHT: (C)2008,JPO&INPIT
