Production of Foam Formation Mullite Porous Body Using Slip Casting and Aluminum Powder

Foaming of green bodies is induced using an acrylic mold; namely, the green body is produced by two simultaneous reactions, a hydrogen generation reaction involving aluminum particles and sodium hydroxide, and a gelling and setting reaction involving sodium silicate and sodium aluminate. Foam format...

Zusammenfassung:	Foaming of green bodies is induced using an acrylic mold; namely, the green body is produced by two simultaneous reactions, a hydrogen generation reaction involving aluminum particles and sodium hydroxide, and a gelling and setting reaction involving sodium silicate and sodium aluminate. Foam formation ratio, porosity and pore size of green bodies are examined for various particle sizes and amounts of aluminum powder added to mixed slurry for the evaluation of green bodies.
