Abstract
Zeolite NaA can be produced with a very short crystallization time, if an alumino-silicate gel of particular properties is prepared and heated at about 95.degree. C. The gel which is prepared by combining solutions of sodium aluminate and sodium silicate must contain a limited amount of water, be of a single phase and having a high viscosity. Gels of this nature can be heated for a fraction of an hour to yield essentially completely crystallized Zeolite NaA with no crystalline impurities.
