<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing fine zeolite with no amorphous substance or a very little amount of amorphous substance because when fine zeolite crystal with a particle size 0.5μm or less is manufactured by crushing zeolite, the zeolite is made amorphous, crystallinity is degraded, and original performance of the zeolite can not be achieved. <P>SOLUTION: The fine zeolite with the particle size 0.5μm or less obtained by crushing zeolite once is dispersed in an aluminosilicate solution having a specific composition, and is recrystallized to manufacture the fine zeolite with no amorphous substance or a very little amount of amorphous substance. The obtained zeolite fine particle exhibits improved crystallinity, and achieves excellent performance particular to zeolite, such as catalyst characteristics, absorption characteristics, and an ion exchange property. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
