Fabrication of Tubular Mullite-Alumina Porous Ceramics by Polymer-Aided Extrusion

Abstract:

Article Preview

Mullite-alumina porous ceramics were fabricated by polymer-aided extrusion through using natural kaolin and alumina as starting materials. The physical and chemical properties of porous ceramics were investigated. The results showed that the approach of using kaolin as starting material offers many benefits such as low cost, big processing capacities, low mullitization temperature and unique microstructure. The porous ceramics with high strength, high porosity, narrow pore size distribution, high permeability and good thermal-shock behavior was obtained by modifying preparation conditions.
