综述了大沸石单晶的生长技术。大是指一维至少为 50μm，比传统水热结晶通常产生的晶体大得多。将展示如何在实验室中以多种方式修改水热结晶，以生产大晶体。这些用于晶体生长的各种方法将结合理解水热结晶机制进行讨论，并简要考虑沸石在自然界中作为大晶体的出现。还回顾了非水溶剂热和低温方法，例如使用凝胶进行沸石晶体生长。讨论的重点是硅酸盐固体，并包含对 2004 年中期之前的文献的回顾，包括我们自己最近的一些结果。
Techniques for the growth of large single crystals of zeolites are reviewed. Large is taken to mean at least 50μm in one dimension, considerably more sizeable than the crystals commonly produced by a conventional hydrothermal crystallisation. It will be demonstrated how hydrothermal crystallisation can be modified in the laboratory, in a number of ways, to allow large crystals to be produced. These various approaches used for crystal growth will be discussed in relation to understanding hydrothermal crystallisation mechanism and also by considering briefly the occurrence of zeolites as large crystals in nature. Also reviewed are non-aqueous solvothermal and low temperature methods, such as the use of gels, for zeolite crystal growth. The discussion is focussed upon on silicate solids, and contains a review of the literature until mid 2004, including some of our own recent results.
