英文摘要	the synthesis of zeolite x is characterized by uv raman spectroscopy, nmr spectroscopy, and x-ray diffraction. uv raman spectra of the liquid phase of the synthesis system indicate that ai(oh); species are incorporated into silicate species, and the polymeric silicate species are depolymerized into monomeric silicate species during the early stage of zeolite formation. an. intermediate species possessing raman bands at 307, 503, 858 and 1020 cm(-1) is detected during the crystallization ill the solid phase transformation. the intermediate species is attributed to the beta cage, the secondary building unit of zeolite x. a model for the formation of zeolite x is proposed, which involves four-membered rings connecting to each other via six-membered ring to form beta cages, then the beta cages interconnect via double six-membered rings to form the framework of zeolite x.
