Abstract: The crystal structure of B-Si pentasil zeolite molecular sieve was determined by means of the x-ray diffraction for polycrystalline samples and refined by Rietveld method.The parameters of the unit cell are a=19.983(1)Å;b=19.773(1)Å;c=13.303(1)Å.Its space group is D2h16-PnmaThe framework topology found agrees with reported Si-Al ZSM-5zeolite molecular sieves.It is concluded from the structural determination that Bis introduced into the framework of this sample.
