Procedure

The sodium aluminate solution was reacted with the calculated amount of sodium silicate solution under vigorous agitation in a 15 liter vessel (temperature of the solutions 20° to 80° C.). A sodium aluminosilicate that was x-ray amporphous was produced as primary precipitation product in an exothermic reaction. After ten minutes of vigorous agitation the suspension of the precipitation product was either
