BOUND STRUCTURE OF CERAMIC TO METAL AND ITS BINDING

PROBLEM TO BE SOLVED: To provide a method for simply binding a ceramic molded product to a metal member at a low cost in high productivity, while ensuring the mechanical strengths of members, by inserting the metal member into the ceramic molded product having a penetrated hole, a depression or a notch, and subsequently sintering the combination to produce the ceramic sintered product. SOLUTION: This method for binding a ceramic molded product to a metal member comprises subjecting a ceramic raw material mixed with an organic binder to an injection molding process, (A) forming a penetrated hole, a depression or a notch 3a in the formed flat plate-like molded product 3A, (B) thermally treating the processed molded product to produce the binder-removed molded 3B, (C) calcining the molded product 3B to produce the partially sintered molded product 3C, (E) inserting a metal member 2 having a small diameter of about 0.1-0.2 mm into the penetrated hole 3b of the molded product 3C, and (F) sintering the inserted metal member 2 and the ceramic molded product 3C in a sintering device to produce the ceramic sintered product 1. The ceramic sintered product is contracted in the sintering process to pressure-weld and bind the ceramic sintered product to the metal member 2. It is preferable that a hollow portion is formed on the binding surface 4 of the metal member 2 to the ceramic.
