PROBLEM TO BE SOLVED: To obtain a member for baking a ceramic, capable of not being corroded with vapor of PbO and improving spalling resistance and durability, comprising a spinel. SOLUTION: MgO is mixed with Al2 O3 in the molar ratio of MgO to Al2 O3 of >=1.0 and calcined in the atmosphere at 1,200-1,300 deg.C to give calcined powder. The calcined powder is ground, molded into a fixed shape and baked at 1,600-1,700 deg.C to give the objective member for baking a ceramic, composed of a spinel. |
