Reaction Conditions

Reaction Steps

By using the above-mentioned three kinds of starting materials, the sodium aluminate solution was heated at 90° C. and stirred, and to which was mixed sodium silicate solution heated at 75° C. over a period of 12 minutes (maintaining a temperature of not lower than 80° C.) such that the total amount of the reaction solution was 5 kg in a 10-liter stainless steel container, in order to form a sodium aluminosilicate which as a whole was in a homogeneous gel-like form having the below-mentioned molar composition:
