Abstract
A method of manufacturing a ceramic body having continuous three-dimension through-out holes which can be preferably employed as a filter for filtration of non-metallic inclusions in a molten metal and as a porous plug for introducing a gaseous medium for floating up the non-metallic inclusions. An organic body having a three-dimensional construction is placed in a casting mold, a slip of a ceramic material is poured into the mold, and after drying, the molded body is baked to effect decomposition of the organic porous body. Thus the ceramic body is provided with through-out holes communicating with to each other three-dimensionally together with a high mechanical strength.
