  • Novel mullite ceramic foams with high porosity and ...

    2018-4-1 · A series of alumina ceramic foams within wide range of porosity can be obtained (see Table S1) by varying solid loading and SDS addition amount. The microstructure of alumina foams with different porosities is shown in Fig. 1. The average pore sizes of all alumina ceramic foams are in the range of 50–150 µm. It is found that there is a significant dependence of pore and wall morphology on porosity …
