Abstract
Oxalic acid is employed in a precursor mixture containing at least one milled alpha alumina powder having a particle size of 0.1 to 6 microns, boehmite powder that functions as a binder of the alpha alumina powders, and at least one burnout material having a particle size of 1-10 microns to provide a porous body having enhanced pore architecture in which extrusion cracks can be reduced. The presence of oxalic acid in such as precursor mixture can reduce and even eliminate NOx emission during a high temperature heat treatment process.
