Abstract: PURPOSE: To provide an alumina-mullite porous refractory sheet having excellent thermal shock resistance and remarkably improved high-temperature deflection resistance at e.g. 1,600deg.C and suitable for the baking of a ceramic substrate and slumina ceramic and provide a method for the production of the refractory sheet. CONSTITUTION: The objective alumina-mullite porous refractory sheet is a fired material composed of 50-85 wt.% aggregate component composed of electromelted and/or sintered alumina and electromilted mullite and having a particle diameter of 10-150 μm, 15-50 wt.% binder component composed of alumina and mullite and inevitable impurities and having a porosity of 10-40%. The method for the production of the alumina-mullite porous referactory sheet comprises the mixing of an organic binder, water and the aggregate to a binder composed of alumina and fine silica powder and/or clay at a compositional ratio to give the objective binder component after burning, the kneading of the mixture, the forming of the kneaded mixture to a sheet and the burning of the sheet after drying.
