摘要
The (Si, Al) ordering scheme in the framework of zeolites is reviewed. The (Si, Al) distribution in the tetrahedral framework of zeolites may be mainly ordered or mainly disordered. According to a generally accepted model during crystallization of a zeolite from an alumino-silicate (true or colloidal) solution, rings or cages of tetrahedra are formed around a hydrated cation. These act as a template, and so the newly formed cage tends to a definite, constant shape.
