PROBLEM TO BE SOLVED: To produce inorganic foam which has closed cells and excellent external appearance. SOLUTION: In the case of producing the inorganic foam by mixing SiO2 -Al2 O3 -based reactive inorganic powder A, alkali metal silicate B, water C and a foaming agent to form a curable inorganic composition, foaming and curing the curable inorganic composition, before the mixed curable inorganic composition starts foaming, vibration especially vibration in the facial direction is given to the curable inorganic composition. |
