摘要：

An ANA-type microporous crystalline borosilicate has been synthesized hydrothermally from gels containing potassium ions. Refinement by Rietveld analysis of X-ray diffraction pattern confirmed B-ANA to be isostructural with leucite (KAlSi2O6). B-ANA displays an unusually high thermal stability, as demonstrated by the lack of any signals due to trigonal boron species in the B-11 MAS NMR spectra of the calcined material.
