Fabrication of Porous Mullite Ceramics with High Porosity Using Foam-gelcasting

摘要：

　　In this paper,porous mullite ceramics with an apparent porosity up to 81% were fabricated by foam-gelcasting using mullite powder as raw material with solid loading of 40 vol.%.The monomers content and sintering temperature have obvious effect on the properties of porous mullite ceramics.The apparent porosity of the prepared samples was in the range of 75~82%,compressive strength,was in the range of 3.0~16.02 MPa,and thermal conductivity was between 0.14 and 0.47 W/(m·K).A complex porous microstructure was formed,where large spherical pores contained small cellular pores on their internal walls.
