Procedure
The same starting materials as those of Example 1 were used. That is, the sodium aluminate solution was heated at 90° C. and was stirred, and to which was mixed the sodium silicate solution heated at 75° C. over a period of 12 minutes (maintaining a temperature of not lower than 80° C.) so that the total amount of the reaction solution was 5 kg in a 10-liter stainless steel container, in order to form a wholly homogeneous gel-like sodium aluminosilicate having the following molar composition.
