摘要: 应用多晶X射线衍射法测定了B-SiPentasil型沸石分子筛的晶体结构并经Rietveld法修正.其晶胞参数为:α=19.983(1)Å;b=19.973(1)Å;c=13.303(1)Å.空间群为D2h16-Pnma.晶体的骨架结构与所报导的Si-AlZSM-5相似.结构测定的结果表明:硼原子进入了沸石分子筛的骨架.

Abstract: The crystal structure of B-Si pentasil zeolite molecular sieves has been determined by means of the X-ray diffraction for polycrystalline materials and has been refined with Rietvelds method. The parameters ofthe cell are : a= 19.983(1)Å; b= 19.973(1) Å; c= 13.303(1)Å. Its space group is D2h16-Pnma, The framework topology found agrees with reported Si-Al ZSM-5 zeolite molecular sieves. It is concluded from the structure detemination that Bis introduced into the framework of this sample.
