    is also illustrated by the fact that they transform to the cubic langbeinite structure at relatively low temperature (≈200 °C). In conjunction with our prior studies on Na2Mg2(SO4)3 (complex monoclinic cell, which also transforms to langbeinite at elevated temperature), this work highlights the flexibility of the langbeinite structure to accommodate high levels of Na ions, thus offering another potential

    anhydrous compounds. Exothermic peaks diagnostic of acid-base reactions were observed in all reactions except the CuCO3·Cu(OH)2 reaction which showed an endotherm in the DTA curve. Pathways have been postulated on the basis of the analysis of the reaction products and the final stoichiometries of the reactions have been determined.
    摘要 MgCO3、CaCO3、SrCO3、BaCO3、MnCO3、ZnCO3ZnO、CoCO3·Co(OH)2、CuCO3·Cu(OH)2、3MgCO3·Mg(OH)2·3H2O和NiCO3·2Ni(OH)2的反应·通过热重分析和差热分析技术研究了2H2O和K2S2O7。发现重量损失的初始反应温度通常低于相应无化合物的分解温度。除了在 DTA 曲线中显示吸热的 CuCO3·Cu(OH)2 反应外,在所有反应中都观察到了诊断酸碱反应的放热峰。基于对反应产物的分析假设了途径,并确定了反应的最终化学计量。

    Abstract Deuterium isotope effects in the thermal stability, enthalpy change, and kinetic parameters were examined by means of TG-DSC recorded simultaneously for the dehydration stages of The thermal stability and enthalpy change for the hydrate were smaller than those for its deuterium analog in stage (1). In addition, the rate constant for the hydrate was larger than that for the deuterate in this
