PURPOSE:To obtain the calcined body of the title molded body having high bending strength and superior thermal shock resistance by calcining a fused silicon oxide molded body at a specified temp. CONSTITUTION:A slurry consisting of fused silicon oxide powder, an org. binder and water is poured into a water absorbing mold and molded. This molded body is dried at such a drying rate that it does not crack and the dried molded body is further dried by heating at 100-150 deg.C to obtain a fused silicon oxide molded body. This molded body is slowly heated, held at a medium temp. and calcined by further heating to 1,190-1,200 deg.C. |
