1. A method for making silicalite MFI particles, the method comprising:
(a) providing a mixture in water of dissolved tetrapropylammonium bromide and ammonium fluoride and dispersed silicalite MFI seeds; (b) adding amorphous, colloidal silicon dioxide to the mixture to form a homogeneous gel, wherein the ratios of the quantities of silicalite MFI seeds, tetrapropylammonium bromide, ammonium fluoride and silicon dioxide are about 424:14:1:38; and (c) heating the homogeneous gel at about 180° C. for about 4 days.
