The study was focused on changes in the electrical and structural parameters of nontronite as a function of temperature in the range of 25 °C–325 °C. Nontronite during heating loses water from the interlayer space. Structural changes in the mineral were monitored by X–ray powder diffraction, thermal analysis, and dielectric spectroscopy. The experiments showed that between 35 °C–60 °C the mineral loses only a small part of water bound between the layers. This resulted in a significant change in the distance between the layers from 15.2 Å to 13.0 Å and a 100% increase in low–frequency electric permittivity. The main process of losing interlayer water molecules starts at 60 °C and finishes close to 160 °C. Interlayer water responds to the external electric field, causing an increase in electric permittivity. Analysis of dielectric relaxation gave valuable insight into the dynamics of weakly bound interlayer molecules–water in the case of natural nontronite.

该研究的重点是在温度范围为25°C–325°C的范围内，绿脱石的电气和结构参数的变化。加热过程中的绿脱石从层间空间流失水。矿物的结构变化通过X射线粉末衍射，热分析和介电光谱法进行监测。实验表明，在35°C至60°C之间，矿物仅损失了两层之间的一小部分水分。这导致层之间的距离从15.2Å到13.0Å发生了显着变化，并且低频电容率增加了100％。损失夹层水分子的主要过程始于60°C，最后接近160°C。层间水响应外部电场，导致介电常数增加。
