Abstrakt: Simulation of X-ray diffraction patterns on the basis of the models of one-dimensional disordered crystals was used to investigate the structure of the dehydrated phase produced by dehydration of Mg-Al and Ni-Al layered double hydroxides at a temperature of ∼473-498 K. It was found that the removal of water molecules transforms the initial structure, which is a mixture of 3R 1 and 2H 1 polytypes, into a structure that comprises preferentially fragments of 3R 2 and 1H polytypes and has some turbostratic disorder.
Contributed Indexing: Keywords: diffraction-pattern simulation; hydrotalcite structure; layered double hydroxides; turbostratic disorder
