β沸石的四面体骨架结构沿沿着（001）方向是无序的。无序结构通过（001）平面上的a/3和/或B/3位移与三斜、单斜和四斜对称的三种有序多型结构相关。三个相互垂直的12环通道系统的特征是三个有序的多型体和无序的β结构。提出的骨架结构与已知的衍射，吸附和阳离子交换性能的沸石β是一致的。
The tetrahedral framework structure of zeolite beta is disordered along (001). The disordered structure is related by a/3 and/or b/3 displacements on (001) planes to three ordered polytype structures with triclinic, monoclinic, and tetragonal symmetry. Three mutually perpendicular 12-ring channel systems are characteristic of the three ordered polytypes and the disordered beta structure. The proposed framework structures are consistent with the known diffraction, sorption an cation exchange properties of zeolite beta.
