    Notes: q =803 K) have been investigated via the Vickers microhardness measurements, scanning electron microscopy and differential scanning calorimetry. On the basis of Kissinger’s analytical equation of the DSC thermograms, the overall activation energies associated with the transformation processes are evaluated. The activation energy associated with the formation of the GPB zones and δ’ phase is determined as 82.433 kJ/mol. Whereas the energy of their dissolution is 139.78 kJ/mol. The activation energy associated with the formation of the S’ phase is determined as 106.88 kJ/mol. In addition, the microstructural examination of the samples after various aging temperatures revealed that the resultant precipitates are intergranular.

    Description / Table of Contents: Zusammenfassung Das Verhalten von Ceroxycarbonat bei der thermischen Zersetzung wird beschrieben. DTA, TG, DTG und Röntgendiffraktometrie wurden zur Untersuchung herangezogen. Die thermische Zersetzung erfolgt in statischer Luftatmosphäre bei einer Aufheizgeschwindigkeit von 10° min−1 in drei Schritten. Der erste Schritt bei 58 °C ist der Dehydratisierung, der zweite bei 200 °C dem Austritt von Kristallwasser und der letzte bei 235 °C der Abspaltung von CO2 zuzuschreiben. Für die Kristallwasserabgabe wurde eine Aktivierungsenergie von 59.48 kJ · mol−1 und für die CO2-Abspaltung von 82.33 kJ · mol−1 berechnet.

Результа ты показали, что термическое разл ожение оксикарбонат а церия в статической а тмосфере воздуха при скорости нагрева 10°/мин протека ет в три стадии. Первой стадие й при 58° является дегид ратация, второй при 200 °C-удалени е кристаллизационно й воды, а третьей стадие й при 235 °C-выделение дву окиси углерода. Энергии акт ивации второй и третьей стад ий равнялись, соответ ственно, 59,48 и 82,33 кдж·моль−1
    Notes: Abstract This work describes the thermal decomposition behaviour of cerium oxy-carbonate. DTA, TG, DTG and X-ray examinations were performed. The results indicate that the thermal decomposition of cerium oxy-carbonate in static air at a heating rate of 10 deg min−1 involves three steps: dehydration at 58 °C, removal of crystal water at 200 °C and CO2 release at 235 °C. The activation energies of removal of crystal water and carbon dioxide release were found to be 59.48 and 82.33 kJ mol−1, respectively.

    Description / Table of Contents: Zusammenfassung Mittels Thermogravimetrie, Differentialthermoanałyse und röntgendiffraktion wurde die thermische Zersetzung von Ammonium-zer(III)-karbonat (ACeK) [NH4CeO(CO3)] untersucht. Die Ergebnisse zeigen drei jeweils mit Gewichtsverlust verbundene endotherme Zersetzungsschritte. Während des ersten Schrittes wird bei 65.5 °C adsorbiertes Wasser, anschließend im zweiten Schritt bei 214.8 °C Ammoniak und letztendlich im dritten Schritt bei 263.6 °C Kohlendioxid abgegeben.

Результаты показали три эндотермические ста дии разложения, сопровождающиеся по терей веса. На первой с тадии при температуре 65,5 °С проис ходит выделение адсорбиро ванной воды, на второй — при температуре 214,8 °С рьои сходит выделение аммиака, а н а третьей стадии при т емпературе 263,6 °С — выделение двуок иси углерода.
    Notes: Abstract The thermal decomposition of ammonium ceryl(III) carbonate (ACeC) [NH4CeO(CO3)] was investigated by thermogravimetry, differential thermal analysis and X-ray diffraction. The results showed three endothermic stages of decomposition, each involving a loss in weight. The first stage, at 65.5 °C, is characteristic of the removal of adsorbed water, the second stage, at 214.8 °C, is associated with ammonia release, and the third stage, at 263.6 °C, relates to the removal of carbon dioxide.
