Abstract:
1. A porous ceramic oxide membrane support formed by sintering a green body containing refractory grains and grains of at least one reactive binder precursor, comprising: refractory grains of at least one simple or compound ceramic oxide, wherein the coefficient of thermal expansion of the refractory grains is greater than about 8×10 at least one reactive binder precursor comprising grains of an element in a non-oxidized state; wherein the green body is sintered in an oxidizing atmosphere, and during sintering the grains of the reactive binder precursor react with the oxidizing atmosphere to form a reaction bond to bind the refractory grains; and wherein the mean pore size of the membrane support is greater than about 1 micron.
