Gel casting of silicon nitride foams using biopolymers as gelling agents
Si3N4-based foams were prepared by the gel casting route using egg-albumen, agar-agar, or methylcellulose as biopolymer gelling agents. Microstructural, permeability, and mechanical properties of the foams were determined. The use of a variety of environmentally friendly gelling agents produced Si3N...
