METALLIZED CERAMIC MOLDING, PROCESS FOR PRODUCING THE SAME AND PELTIER DEVICE

摘要

[PROBLEMS] To provide a metallized nonoxide ceramic molding that exhibits enhanced bonding strength between metal layer and substrate and enhanced boding durability, and provide a process for producing the same. [MEANS FOR SOLVING PROBLEMS] The process for producing a metallized molding is characterized by including the heating step of heating a nonoxide ceramic molding to a temperature 300‹C lower than the oxidation initiation temperature of the nonoxide ceramic or higher temperature substantially without solid dissolution of oxygen during the temperature rise; the oxidation step of bringing the nonoxide ceramic molding, as a substrate, heated by the heating step into contact with an oxidative gas and maintaining the same at a temperature higher than the oxidation initiation temperature of the nonoxide ceramic so that the nonoxide ceramic molding has its surface oxidized to thereby form an oxide layer; and the metallizing step of forming a metal layer on the surface of the oxide layer of the nonoxide ceramic molding having the oxidized layer provided on its surface in the oxidation step. ® KIPO & WIPO 2007
