A. Joyama et al., PRODUCTION OF FOAM FORMATION MULLITE POROUS BODY USING SLIP CASTING AND ALUMINUM POWDER, Nippon Seramikkusu Kyokai gakujutsu ronbunshi, 105(4), 1997, pp. 356-360
Foaming of green bodies is induced using an acrylic mold; namely, the
green body is produced by two simultaneous reactions, a hydrogen gener
ation reaction involving aluminum particles and sodium hydroxide, and
a gelling and setting reaction involving sodium silicate and sodium al
uminate, Foam formation ratio, porosity and pore size of green bodies
are examined for various particle sizes and amounts of aluminum powder
added to mired slurry for the evaluation of green bodies.
