ABSTRACT:
The present invention related to a method for joining ceramic members and an insertion member to be employed in the joining method. In the present invention, ceramic members are heated by the induction heating in a state that a heating ceramic member having a conductivity larger than those of the ceramic members to be jointed is intervened between the ceramic members to be jointed. In this induction heating, the heating ceramic member having a larger conductivity is mainly heated and the temperature of the butting portion is raised up to a temperature needed to join the ceramic members. Upon joining the ceramic members, it is desirable to press the butting portion but is not necessarily needed. In the case without the pressing, it is desirable to form a layer of a joining agent on each of the butting surfaces of the heating insertion member beforehand.
