PRODUCTION OF INORGANIC COMPOSITE OXIDE FOR NONCOMBUSTIBLE MATERIAL AND COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To produce an inorg. composite oxide for a noncombustible material having low initial viscosity. SOLUTION: An aluminum-contg. compd. is added to an aq. soln. of silicate contg. an alkali metal and/or an alkaline earth metal. Silica is then added and they are heated at <=150 deg.C. The ratio of nM to Si [M is alkali metal and/or alkaline earth metal and (n) is the valance of M] in the silicate aq. soln. contg. the alkali metal and/or the alkaline earth metal is preferably 0.1-5.0.
