Abstract

A simple direct foaming and casting process using ovalbumin based aqueous slurries for fabricating alumina-zeolite ceramic foam was demonstrated. 50 to 90 vol.% of alumina was used with zeolite of clinoptilolite type. Meanwhile, yeast was used as pore former agent and ovalbumin as a binder to bind the particles and encouraging foam formation. A ceramic foam with 90 vol.% of alumina showed the highest porosity 65.09% and pore size up to 106 μm. The performance and utilization of these ceramic foams manufactured using this method may have a potential use in a range of applications including catalysis and filter.
