ABSTRACT:
Disclosed herein is a method of preparing crystalline, zeolitic aluminosilicates with SiO.sub.2 /Al.sub.2 O.sub.3 ratios of 20 or more. The method provides a two-stage crystallization process which avoids the formation of secondary crystalline phases. The first stage is conducted at a temperature between 240.degree. C. and 325.degree. C. for between about 1 and 20 minutes. The second stage is conducted in an open vessel at a temperature between about 50.degree. C. and 100.degree. C. for about 40 to 240 hours.
