众所周知的分子筛种类包括铝硅酸盐沸石，1包括磷取代的铝硅酸盐，2· 3微孔二氧化硅多晶型物，4和最近发现的铝磷酸盐分子筛。5.现在又合成了另一类新的叠层微孔骨架氧化物分子筛，硅铝磷酸盐。这些新材料具有沸石和铝磷酸盐的性质，但在许多方面是独特的。它们应该用作分离和纯化分子物质的吸附剂，用作催化剂或催化剂载体，以及用作离子交换剂。新的硅铝磷酸盐材料家族（SAPO-n）7具有迄今已知的约13种三维微孔框架结构的结构多样性。这些包括新结构SAPO-40、SAPO-41和SAPO-44，与沸石菱沸石（SAPO-34）、硅镁矾（SAPO-35）、八面沸石（SAPO-37）和A（SAPO-42）拓扑相关的结构，与在铝磷酸盐中发现的新结构类型拓扑相关的结构，包括SAPO-5、SAPO-11、SAPO-16和SAPO-17。
The well-known classes of molecular sieves comprise the aluminosilicate zeolites, 1 including phosphorus-substituted alumi-nosilicates, 2· 3 the microporous silica polymorphs, 4 and the recently discovered aluminophosphate molecular sieves. 5 Now another novel class of crystallinemicroporous framework oxide molecular sieves, the silicoaluminophosphates, has been synthesized. 6 These new materials have properties both of zeolites and of alumino-phosphates yet are unique in many ways. They should find uses as adsorbents for separation and purification of molecular species, as catalysts or catalyst supports, and as ion-exchange agents. The new family of silicoaluminophosphate materials (SAPO-n) 7 exhibits structural diversity with some 13 three-dimensional microporous framework structures known to date. These include novel structures, SAPO-40, SAPO-41, and SAPO-44, structures topologically related to thezeolites, chabazite (SAPO-34), levynite (SAPO-35), faujasite (SAPO-37), and A (SAPO-42), structures topologically related to the novel structure types found in the aluminophosphates, including SAPO-5, SAPO-11, SAPO-16, and
