ABSTRACT:
Aluminium nitride ceramics improved in heat radiation property used as a substrate for integrated circuits and package material, comprising a sintered article consisting mainly of aluminium nitride and having a thermal conductivity higher than 100.multidot.W/m.multidot.K at room temperature and a surface layer consisting mainly of aluminium nitride or oxide glass deposited on the sintered article. A paste of aluminium nitride powder or oxide glass powder is coated on a surface of the sintered article of aluminium nitride and then is sintered to prepare a dense smooth surface layer.
