ABSTRACT:
Synthetic crystalline alumino-silicate zeolites are prepared by combining reactant quantities of alumina, silica, sodium hydroxide and water with zeolite-forming alumino-silicate seeds having the composition 16 Na.sub.2 O: 2 to 9 Al.sub.2 O.sub.3 : 15 SiO.sub.2 : 500 to 2000 H.sub.2 O. The seed compositions may be used to produce Type A, X and Y crystalline alumino-silicate zeolites.
