摘要：

Porous anorthite/mullite composites with different mullite content were fabricated by foam-gelcasting, using CaCO3, SiO2, alpha-Al2O3 as raw material for anorthite phase and mullite powder for mullite phase. Effects of mullite powder content on bulk density, porosity, compressive strength and thermal conductivity of the porous composite ceramics were researched. Mullite powder content has great effect on microstructure and properties of the porous anorthite/mullite composite ceramics. The apparent porosity of the prepared porous anorthite/mullite composite ceramics is in the range of 58.7 similar to 77.5 %, the compressive strength is between 4.2 and 30.9 MPa, and the thermal conductivity is in the range of 0.18 similar to 1.47 W/(m.K).
