摘要：

Atomic force microscopy (AFM) has been employed to study the surface of the natural zeolite heulandite. Images on a macroscopic scale exhibit growth spirals on the outer surface and cleavage tips an the (010) surface, both with terraces separated from each other by half of the unit cell length b. The angle of the cleavage tips depends on the cleaving direction. Molecular resolution is obtained when measured in 0.1 M NaOH, 0.1 and 1 M KOH, and 6.66 M CsOH. The influence of immersion time, the nature of the ion species, and the ion concentration on the unit cell has been investigated. The lattice constants varied around the bulk values.
