Synthesis of faujasite.

摘要

In a method for preparing faujasite, a gel is formed comprising a mixture of water, alkali metal aluminate and alkali metal silicate. The gel is then broken by subjecting the gel to high shear agitation to convert the gel to a homogeneous, pourable mixture. The resultant mixture is then aged for at least 6 hours at a temperature of at least 15 DEG C before being crystallized to produce faujasite in the form of platelets having a particle size of 0.1 microns or less.
