Fabrication of Cordierite Honeycomb from Fly Ash


Article Preview

In the study, we attempted to synthesize the cordierite by the reaction of fly-ash and alumina, silicon dioxide, magnesia powders. And also porous cordierite honeycomb filte r for air purification was fabricated from the combination of synthetic cordierite using fly as h and pore forming agent. As the extrusion processing parameters of honeycomb, binder formul ation and extrusion conditions were investigated. Graphite addition was effective for the reduce ment of extrusion pressures. Porous cordierite honeycomb was fabricated with high porosity ( 58%), and good compressive strength (69MPa) with 30wt% graphite at low sintering tempera ture(1150oC).
