Abstract: Silica powder is added to a primary mixture consisting of alumina powder and graphite powder, and is mixed therewith. A binder is added to the resultant secondary mixture and is well mixed therewith. The mixture thus obtained is granulated. The granulated product is placed in a rubber mold, and pressure is applied uniformly thereto to mold it. The molded product is fired but not sintered at a temperature between 850.degree. and 950.degree. C., preferably 900.degree. C., which allows unreacted alumina and silica to remain in the final fired-product. Thus, a nozzle consisting of a fired body having a cavity volume index (the sum of the volume of open and closed pores/the volume of the fired body) of 0.15-0.25 including 6-60% of closed pores therein is manufactured.
