Mössbauer, Raman, X-ray diffraction and X-ray photoelectron spectroscopies were used to examine the effects of temperature on the structure of two aluminoceladonite samples. The process of oxidation of Fe²⁺ to Fe³⁺ ions started at about 350 °C for the sample richer in Al and at 300 °C for the sample somewhat lower Al-content. Mössbauer results show that this process may be associated with dehydroxylation or even initiate it. The first stage of dehydroxylation takes place at a temperature > 350 °C when the adjacent OH groups are replaced with a single residual oxygen atom. Up to ~500 °C, Fe ions do not migrate from cis-octahedra to trans-octahedra sites, but the coordination number of polyhedra changes from six to five. This temperature can be treated as the second stage of dehydroxylation. The temperature dependence on the integral intensity ratio between bands centered at ~590 and 705 cm⁻¹ (I₅₉₀/I₇₀₅) clearly reflects the temperature at which six-coordinated polyhedra are transformed into five-coordinated polyhedra. X-ray photoelectron spectra obtained in the region of the Si2p, Al2p, Fe2p, K2p and O1s core levels, highlighted a route to identify the position of Si, Al, K and Fe cations in a structure of layered silicates with temperature. All the measurements show that the sample with a higher aluminum content and a lower iron content in octahedral sites starts to undergo a structural reorganization at a relatively higher temperature than the less aluminum-rich sample does. This suggests that iron may perform an important role in the initiation of the dehydroxylation of aluminoceladonites.

穆斯堡尔（Mössbauer），拉曼（Raman），X射线衍射和X射线光电子能谱用于检查温​​度对两个铝硅藻土样品结构的影响。对于富含Al的样品，Fe ²⁺氧化为Fe ³⁺离子的过程始于大约350°C，而对于Al含量略低的样品，其氧化过程始于300°C。Mössbauer的结果表明，该过程可能与脱羟基反应有关，甚至引发脱羟基反应。当相邻的OH基团被一个残留的氧原子取代时，脱羟基的第一阶段将在> 350°C的温度下进行。高达〜500 °C，Fe离子不会从顺八面体迁移到反式-八面体站点，但多面体的配位数从六变为五。该温度可以视为脱羟基的第二阶段。温度对以〜590和705 cm ^-1为中心的谱带之间的积分强度比的依赖性（I ₅₉₀ / I ₇₀₅）清楚地反映了六配位多面体转化为五配位多面体的温度。在Si2p，Al2p，Fe2p，K2p和O1s核心能级区域获得的X射线光电子能谱突显了一种识别Si，Al，K和Fe阳离子在层状硅酸盐结构中随温度变化的位置的途径。所有测量结果都表明，与铝含量较低的样品相比，八面体位置的铝含量较高且铁含量较低的样品开始在相对较高的温度下进行结构重组。这表明铁可能在铝硅藻土的脱羟基反应中起重要作用。
