Abstract

The aim of this paper is to determine the hydration characteristics of Na-hectorite exchanged Cu2+ or Ca2+. The number and positions of H2O molecules are determined by an indirect method based on the comparison between theoretical and experimental XRD patterns. The obtained results on air-dried Hectorite-Cu (H-Cu) and Hectorite-Ca (H-Ca) showed that these samples are characterised by 12.49 A and 15.10 A basal spacing respectively. These values correspond respectively to one and two water layers in the interlamellar space.

模拟合成的Na-Hectorite的XRD谱图和结构性质

本文的目的是测定Na-hectorite交换Cu2+或Ca2+的水化特性。通过对理论和实验XRD图谱的比较，采用间接方法确定了水分子的数目和位置。经风干的Hectorite-Cu (H-Cu)和Hectorite-Ca (H-Ca)样品的基间距分别为12.49 A和15.10 A。这些值分别对应于层间空间中的一个和两个水层。
