ABSTRACT:
Crystalline compositions, e.g. zincosilicates, which contain 3-membered rings and have a framework density (FD) of less than 21 tetrahedral atoms per cubic nanometer, and their method of preparation are disclosed. The compositions may be used as ion-exchangers, adsorbents, catalysts, e.g. hydrocarbon conversion catalysts, and catalyst supports.
