Y型分子筛子具有类似于钻石的近六角形结构。 If the beta cage is used as the structural unit to replace the carbon atom nodes of the diamond, and the two adjacent beta cages are connected with hexagonal columnar cages, that is, the five beta cages are connected together with four hexagonal columnar cages, of which one beta cage is located in the center and the remaining four beta cages are located at the vertex of the tetrahedron, an octahedral沸石晶体结构形成。通过继续与该结构联系，可以获得Y型分子筛结构。在这种结构中，由β笼和六角形柱状笼形成的大笼子是八面的沸石笼，其相互关联的窗孔是十二个二元环，其平均有效孔径为0.74nm，其平均有效孔径为0.74nm，是Y型分子筛子的孔径。 X型分子筛和Y型分子筛结构完全相同，但是Y型分子筛子二氧化硅铝比很高，水热稳定性很强，因此使用了更广泛的使用。
