Abstract

A single-phased anorthite porous ceramics was fabricated by foam-gelcasting technique using α-Al2O3, CaCO3 and SiO2 as starting material. Through adjusting foaming agent concentration and solid content in the slurry, tailored porosity (62–91%), pore size (7–350 μm), thermal conductivity (0.04–0.27 W/m·K) and compressive strength (0.27–13.39 MPa) were obtained. The experimental thermal conductivity was in good agreement with the universal model. The dependence of compressive strength on porosity can be described by the Gibson model.
