Abstract
Porous sintered ceramic material having bulk analytical composition, by weight, of 74-79% alumina and the balance being silica optionally with other oxide and/or impurities naturally occurring from the batch materials, and having a phase composition, by weight, of 50-75% mullite, 23-45% corundum, 0-6% cristobalite and the balance being substantially 2-10% amorphous alumina-silica based phase. Honeycomb structure, molten metal filter and catalytic converter made from the material.
