ZSM-5是近十年来发展的具有广泛应用前景的高硅沸石分子筛。其骨架主要由五元环连结而成,具有十元环孔道(直径约6(?))。空间群为P_(nma)。 大于40μm的均匀完美沸石单晶体,为晶体结构的测定以及与催化性质有密切关系的阳离子交换、扩散、吸附等重要性质的研究所必须。在通常的条件下获得大而完美的沸石单晶体是困难的。单晶的合成,有利于研究沸石晶体的形成与生长机理,是沸石结晶动力学研究的重要课题之一。
ZSM-5 is a high-silica zeolite with a wide range of applications in recent ten years. Its skeleton is mainly composed of five yuan ring link, with ten yuan ring hole (about 6 (?) Diameter). The space group is P_ (nma). Uniform perfect zeolite single crystals larger than 40μm are necessary for the determination of crystal structure and the important properties such as cation exchange, diffusion and adsorption which are closely related to catalytic properties. It is difficult to obtain a large but perfect zeolite single crystal under the usual conditions. Synthesis of single crystal is conducive to the study of zeolite crystal formation and growth mechanism, zeolite crystallization kinetics is one of the important topics.
