Method of manufacturing crystalline microporous material

A method of manufacturing crystalline microporous material, comprising:

• mixing an alkaline liquid, silicon dioxide and at least one crystallization modifier selected from the group consisting of an ammonium ion of the formula R.sub.4 N.sup.+, a phosphonium ion of the formula R.sub.4 P.sup.+ and amine, wherein R is at least one selected from the group selected from the group consisting of hydrogen, C.sub.1 -C.sub.10 alkyls, and C.sub.1 -C.sub.10 aryls, under conditions sufficient to form a gel;
• separating excess liquid from the gel to form particles comprising silicon dioxide and crystallization modifier;
• and
• crystallizing the particles in the absence of added liquid water to form said crystalline microporous material.
