Formation of hierarchical Si3N4 foams by protein-based gelcasting and chemical vapor infiltration
Abstract Silicon nitride foams with a hierarchical porous structure was formed by the combination of protein-based gelcasting, chemical vapor infiltration, and in-situ growth of silicon nitride nanowires. The porosity of the foams can be controlled at 76.3–83.8 vol% with an open porosity of 70.2– 82...
