METHOD FOR FORMING A QUICKLY HARDENING, INORGANIC FOAM

A process is provided for forming a rapid-hardening inorganic foam, based on the reaction of the following two components: (a) a solid component in the form of a reactive powder having at the same time structure-building and pore-forming properties, and (b) a liquid component in the form of an alkal...

Zusammenfassung:	A process is provided for forming a rapid-hardening inorganic foam, based on the reaction of the following two components: (a) a solid component in the form of a reactive powder having at the same time structure-building and pore-forming properties, and (b) a liquid component in the form of an alkali metal silicate (water glass). The reactive powder contains the essential constituents: 45-65% by weight aluminum oxide, 10-20% by weight aluminum nitride, and 5-15% by weight metallic aluminum. The alkali metal silicate has a molar ratio of silicon oxide to metal oxide of 1.0 to 2.2. The two components are mixed in a weight ratio of powder to liquid component of 0.5 to 2 to give a paste from which a foamed body having a bulk density of less than 0.7 g/cm3 is then formed in an exothermal reaction within less than 10 minutes.
