Summary:PROBLEM TO BE SOLVED: To inexpensively manufacture a large quantity of a high quality porous composite ceramic using the incineration residue powder of waste dry cell as a raw material through steps of preparation/kneading/forming/drying/firing with a common extruder without using a clay outer frame or an expensive pressure molding apparatus. SOLUTION: The manufacturing method is carried out by applying a 2 step preparation and forming method using the incineration residue powder of waste dry cell or the like as the raw material. That is, as a preparation 1st step, water and a forming assistant are added to the incineration residue powder of the waste dry cell, uniformly kneaded and aged and as a preparation 2nd step, a pore forming agent, a sintering assistant and water are added and kneaded thereto and finally, the mixture is formed, dried and fired.
