摘要： 用X射线单晶衍射方法测定了晶体尺寸为150μm×100μm的SAPO-5分子筛的晶体结构.结果表明,SAPO-5属六方晶系,空间群P6cc,晶胞参数a=1.3802nm,c=0.8503nm,权重偏离因子Rw=0.043.F-离子位于2个四元环中间.电子探针分析结果表明,硅只取代磷进入SAPO-5分子筛骨架.

Abstract: The SAPO-5 single crystals with the size of 150μ×100μm crystallized in space group P6cc with a=1.3802 nm and c=0.8503 nm.The crystal structure was refined to Rw=0.043.F- anions are located on the wall of the framework between two four-membered rings.Electron probe microanalysis (EPMA) shows that silicon is only substituted for phosphorus.
