摘要：
Levyne type zeolites have been successfully synthesized from gels 4.5Na(2)O-6MeQI-xAl(2)O(3)-30SiO(2)-500H(2)O with 0.6 less than or equal to x less than or equal to 3, at 150 degrees C less than or equal to t less than or equal to 190 degrees C. The Si-29 spectra show unambiguously the presence of two different crystallographic sites in the structure. The combined C-13-NMR and TA data allowed one to interpret the nature of two different types of MeQ(+) ions in the levyne channels.
