Abstract ：
Potassium acetate (KAc) has been successfully intercalated into dickite through immersion method. Prepared complexes were characterized by XRD, FTIR, TG-DTA, XPS and SEM-EDS analyses. The effectiveness of intercalation and influencing factors were also analyzed. The results confirmed that KAc and H2O were successfully inserted into the interlayer of dickite. The results showed that intercalated rate of dickite by KAc were related to aging time, pH value, reaction temperature, and concentration of KAc solution. From the view of energy and environmental protection, reaction time for 24 h was enough to gain a satisfactory intercalation result. While a good intercalated complex can be obtained on the weak alkaline condition of pH value. A higher concentration of KAc solution was beneficial to intercalate and the reaction temperature below 100 degrees C was proved to be favorable for intercalation. (c) 2017 Published by Elsevier B.V.

Abstract ：
Vesuvius is a high-risk volcano and the 1631 Plinian eruption is a reference event for the next episode of explosive unrest. A complete stratigraphic and petrographic description of 1631 pyroclastics is given in this study. During the 1631 eruption a phonolite was firstly erupted followed by a tephritic phonolite and finally a phonolitic tephrite, indicating a layered magma chamber. We suggest that phonolitic basanite is a good candidate to be the primitive parental-melt of the 1631 eruption. Composition of apatite from the 1631 pyroclastics is different from those of CO2-rich melts indicating negligible CO2 content during magma evolution. Cross checking calculations, using PETROGRAPH and PELE software, accounts for multi-stage evolution up to phonolite starting from a phonolitic basanite melt similar to the Vesuvius medieval lavas. The model implies crystal settling of clinopyroxene and olivine at 6 kbar and 1220 degrees C, clinopyroxene plus leucite at a pressure ranging from 2.5 to 0.5 kbar and temperature ranging from 1140 to 940 degrees C. Inside the phonolitic magma chamber K-feldspar and leucite would coexist at a temperature ranging from from 940 to 840 degrees C and at a pressure ranging from 2.5 to 0.5 kbar. Thus crystal fractionation is certainly a necessary and probably a sufficient condition to evolve the melt from phono tephritic to phonolitic in the 1631 magma chamber. We speculate that phonolitic tephrite magma refilling from deeper levels destabilised the chamber and triggered the eruption, as testified by the seismic precursor phenomena before 1631 unrest.

Abstract ：
地开石在陶瓷、涂料、化妆品及填料的工业应用中有着广泛潜力.在本研究中,挑选紫金山Au-Cu矿床中三种典型的地开石(透明、半透明和不透明)和一种矿区分布广泛的淋滤型地开石,通过电子探针(EPMA),X射线粉末衍射(XRD)、傅立叶红外光谱(FT-IR)和场发射扫描电子显微镜(FESEM)表征矿物学特征.EPMA成分对比分析表明,地开石纯度均较高,Al2O3和SiO2质量分数低,FeO质量分数低,白度很高,可以有效地应用到造纸工业中.XRD和FT-IR结果表明,不透明地开石结晶较好,有序度较高,随着透明度的增加,透明地开石的有序度降低,结晶较差.FESEM分析表明,不透明的地开石晶粒发育较好,片层之间堆积紧密,晶粒横向最大尺寸为5 μm,随着透明度的增加,晶粒横向尺寸减小,透明地开石的晶粒为0.2～1 μm;淋滤型地开石可见假六方状片层相互堆积,但由于酸性淋滤作用,片层上有很多小空洞,且片层的边缘溶解,堆积松散,这种淋滤地开石的间层有利于其他高分子材料插入,可用于制备地开石-高分子复合材料.此外,对紫金山Au-Cu矿床地开石的矿物学特征的研究,弄清了地开石之间的形成关系,以及与矿区的成矿关系.

Abstract ：
The thermal decomposition and de-hydroxylation process of dickite-potassium acetate (KAc) intercalated complex was studied using thermogravimetric (TG), differential thermal analysis (DTA), XRD and FTIR. The stability of intercalated complex was affected by heat treatment directly. The TG-DTA results showed that four changes had occurred at 64.5, 118, 301 and 406 A degrees C, which can be attributed to (a) the loss of adsorbed water, (b) loss of the water linked to acetate ion in the layer of dickite, (c) decomposition of KAc, and (d) loss of water through de-hydroxylation, respectively. The XRD and FTIR results showed that when the heating temperature exceeded 400 A degrees C, inner surface hydroxyls and inner hydroxyls lost gradually, generating amorphous meta-dickite. Further researches demonstrated that phase transition temperature of meta-dickite and mullite changed a lot through the intercalated KAc.

Abstract ：
The thermal decomposition process of dickite-potassium acetate (KAc) intercalated complex had been studied by means of thermo-gravimetric (TG), differential scanning calorimetry (DSC), XRD, FTIR and field emission scanning electron microscope (FESEM). The XRD results show that the KAc have been successfully intercalated into dickite through immersion. The stability of intercalated compound is affected by heat treatment temperature. The first step (<300℃) is loss of acetate and the water coordinated to KAc and resulted in the basal d (002) of 1.41 nm turning to 0.908 nm and finally 0.71 nm. And then (400℃-900℃) inner surface hydroxyls, inner hydroxyls, hydrogen bonds formed water and lost, produced amorphous meta-dickite. The last step (900℃-1300℃) is to form mullite and cristobalite. The de-hydroxylation temperature of dickite-KAc decreased about 200℃ and temperature of mullite formation increased about 30℃ compared with dickite. © 2016, Editorial Office of Transactions of Materials and Heat Treatment.
