Abstract: Two novel microporous alumino-borates were synthesized from Na2O-CaO(MgO)-Al2O3-R2O3-R-H2O systems. X-Ray diffraction analysis(XRD), IRspectra and X-Ray photo-electron spec-troscopy analyses (XPS) show that the alumino-borates have novel framework structures. They exhibit charateristic adsoption properties like that of zeolite after the desorption of free water and other molecules within their structures. It is also shown that the micropore size of the alumino-borates are between 5~6Å.
