采用 FT-IR,XRD,SEM,TG,ICP-AES等技术研究了四乙基溴化铵 ( TEABr) -氟化物复合模板剂体系合成 β沸石的晶化过程 .发现本体系 β沸石的合成遵循液相转变机理 ,在诱导期向生长期转变的转折点存在过渡态 ,氟离子对过渡态的形成和转变起到重要作用 .在诱导期初期固相是富铝的 ,但晶体生长期固相硅铝比基本不变 ,表明硅铝同步进入骨架 The crystallization process of β-zeolite synthesized by tetraethylammonium bromide (TEABr) -fluoride complex templating system was studied by means of FT-IR, XRD, SEM, TG, ICP-AES etc. It was found that the synthesis of zeolite β followed the In the liquid phase transition mechanism, there is a transitional state at the turning point between the induction phase and the growth phase, and fluoride ion plays an important role in the formation and transition of the transition state.In the early induction period, the solid phase is aluminum-rich, but the solid-phase silicon Aluminum ratio remained unchanged, indicating that silicon and aluminum into the skeleton simultaneously
