Described is a process to synthesize nano-size Zeolite A from an amorphous
gel precursor which can be synthesized via reaction of NaAlO2, NaOH,
and tetraethoxysilane (TEOS). Zeolite A with particle sizes of 150 nm was
made by transformation of the amorphous precursor in (CH3)4NOH
solution with Zeolite A seeding. The nano-sized Zeolite A can be part of processes
for making non-phosphate detergent where the as-synthesized Zeolite A used as builders,
for making thin films for separation and/or catalysis, for making secondary ordered patterns.
