<p><P>PROBLEM TO BE SOLVED: To provide a colloidal solution capable of crystallizingβ-zeolite in a short of time, and a method for synthesizingβ-zeolite using the same. <P>SOLUTION: The colloidal solution containing Si and Al contains particles having a modal particle diameter of 0.01-0.2μm, wherein the proportion of particles having≥0.5μm is≤3%. The molar ratio of OH/Si is preferably 0.20 to 0.80. When such the colloidal solution is added to a reaction liquid containing Si, Al and tetraethylammonium for crystallization,β-zeolite can be crystallized in a short period of time. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
