Abstract

The environment-friendly egg white protein was used as foaming agents and binders to fabricate Al2O3 ceramic foams. The CaO-SiO 2-MgO-ZnO-TiO2-B2O3 composite sintering additive was added into Al2O3 ceramic foam to develop the mechanical performance of the ceramic foam and facilitate sintering. The porosity, density, compressive strength, pore morphology and grain size of the modified Al2O3 ceramic foam was investigated. The results revealed that, compared with ordinary Al2O3 ceramic foam, although the samples adding sintering additive had lower porosity, larger density and bigger grain, its compressive strength was significantly much higher than samples without sintering additive. The XRD result indicated that samples adding sintering additives had spinel, anorthite and a small amount of mullite phase besides the main corundum phase. Adding sintering additive is a new way to develop the mechanical performance of Al2O3 ceramic foam and facilitate sintering which can help grain growth, thereby improving the mechanical properties.
