Abstract

A simple direct foaming and casting process using ovalbumin based aqueous slurries for fabricating alumina-zeolite ceramic foam was demonstrated. The characteristics of alumina foam were investigated through porosity, pore size, density and strength. 70 to 90 vol.% of alumina was used with zeolite of clinoptilolite type. Meanwhile, yeast was used as pore former agent in order to increase the porosity. Besides that, ovalbumin acted as a binder to bind the particles and encouraging foam formation. An increment in alumina loading has improved the porosity of ceramic foam but slightly reduced its strength. A ceramic foam with 90 vol.% of alumina showed the highest porosity 66.50% with the strength of 3.72 to 2.77 MPa. Therefore, 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.
