电子显微镜获得的沸石表面结构的图像达到了几乎原子分辨率，正如合成八方沸石(FAU，如右图所示)及其六方晶型EMT的研究所证明的那样。相比之下，脱铝形式的Y沸石的表面被覆盖了一层非晶层。在晶体表面上发现的台阶可以得出关于晶体生长的结论。
Almost atomic resolution is achieved in images of the surface structures of zeolites obtained by electron microscopy, as demonstrated in studies of synthetic faujasite (FAU, shown on the right) and its hexagonal polymorph EMT In contrast, the surface of a dealuminated form of zeolite Y was shown to be coated with an amorphous layer. The steps found on the crystal surface allow conclusions concerning crystal growth to be drawn.
