ABSTRACT:
A process for producing a joined ceramic component having a plurality of parallel ceramic tubes and two perforated ceramic plates joined to the both ends of said ceramic tubes, which process comprises: arranging two unsintered ceramic plates each having a plurality of holes, in parallel to each other and also to the floor surface with a given distance provided between the upper plate and the lower plate; inserting a plurality of sintered ceramic tubes into the holes of the upper and lower plates so that the tubes are arranged vertically to the floor surface and in parallel to each other; and sintering the resulting material to join the tubes and the plates into one piece by utilizing the difference in sintering shrinkage factor between them, in which process the sintering is conducted in a state that each tube is hanged from the upper plate and that the lower end of each tube is in one hole of the lower plate placed on or above a setter, with a certain distance provided between the lower end of each tube and the setter so that they do not come in contact with each other during the sintering.
