摘要： A method of forming a nitride ceramic-metal complex material without using a special bonding material. This method comprises bringing a metallic material into contact with the surface of a nitride ceramic material, heating under vacuum the nitride ceramic material so as to dissociate the surface of the nitride ceramic material into nitrogen and a precursor of the ceramic material, thereby allowing the dissociated precursor to react with the metallic material and to achieve bonding between the nitride ceramic material and the metallic material. A nitride ceramic-metal complex material produced by the above method is also proposed.

摘要： A nitride ceramic member is maintained at a vacuum of 1.times.10.sup.-4 Torr or less at a temperature of 1,000.degree. C. or more, and a metal vapor is brought into contact with the surface of the nitride ceramic member. A nitride is reacted with the metal in the surface portion of the ceramic member, and a metallized layer is formed on the surface of the member. If AlN is used as a nitride ceramic material, the AlN member is maintained at the vacuum at the high temperature and a Ti vapor is brought into contact wit the surface of the AlN member to form a TiN coating layer on the surface of the AlN member. A BN or graphite mask is formed on the surface of the nitride ceramic member and the above method is practiced to selectively form a metallized layer on the non-masked member surface. By selectively forming a metallized layer by using AlN, a highly thermal-conductivity substrate having a conductive layer formed on the AlN base can be prepared.
