Joining method of alumina and alumina-containing ceramics and joined ceramic body using it

摘要

An aluminum oxide-based ceramic bonding method according to the present invention comprises the steps of: preparing a bonding material in which a solid component is made of aluminum and at least one oxide; an application step of supplying the bonding material between the ceramic molded bodies including aluminum oxide; and heat-treating the ceramic molded body and the bonding material; the heat treatment step is to oxidize the aluminum of the bonding material and sinter the bonding material and the formed body, and there is an advantage in that a bonding layer having excellent physical properties such as strength .
