无水磷酸铝与二氧化硅的晶体结构紧密相关,具有近乎相同的同质多象变体,其格架由相互交替的AlO_4和PO_4四面体所构成。磷铝石和准磷铝石是含水磷酸盐矿物(AlPO_4·2H_2O),这两种矿物对于水的吸附是不可逆的,完全脱水后,其结构发生根本的变化。1982年美国联合碳化物公司Wilson等成功合成了一系列以铝磷酸盐格架为基础的新型微孔材
The crystal structure of anhydrous aluminum phosphate is closely related to the crystal structure of silica, with almost the same homogeneous multimodal variant, the framework consists of alternating AlO 4 and PO 4 tetrahedra. Both apatite and quasi-apalite are aqueous phosphate minerals (AlPO 4 · 2H 2 O), and the adsorption of these two minerals on water is irreversible. After complete dehydration, their structures undergo fundamental changes. In 1982, Union Carbide Corporation Wilson successfully synthesized a series of new microporous materials based on aluminophosphate framework
