摘要：

Using a novel saponification/peroxide/gelcasting combined route it was possible to produce geopolymer foams with a total porosity of similar to 85 vol%, open porosity as high as similar to 70 vol%, average cell size (D50) of 318 mu m, and possessing a specific surface area of 50 m(2)/g. The in situ formation of surfactants by the saponification reaction of oil in the geopolymer alkaline environment led to increased total and open porosity in comparison to alternative methods for the fabrication of geopolymer foams.
