Abstract

The thermal decompositions ofβ-AlF3 · 3H2O, AlF3 · 3.5H2O, AlF3 · 1.5H2O,β-AlF3 and hydroxyfluorides of aluminium were investigated. The literature data were complemented with X-ray results. The first stages of decomposition are described. The AlF3 hydrates and hydroxyfluorides were used as model systems in order to interpret the thermal behaviour of α-AlF3 in more detail.

Zusammenfassung

Die thermische Zersetzung vonβ-AlF3 · 3H2O, AlF3 · 3,5H2O, AlF3 · 1,5H2O,β-AlF3 und Hydroxyfluoriden des Aluminiums wurden untersucht und die in der Literatur beschriebenen Ergebnisse durch Röntgenuntersuchungen ergänzt. Die ersten Phasen der Zersetzung werden beschrieben. Die AlF3-Hydrate und Hydroxyfluoride des Aluminiums können als Modellsystem genutzt werden, um das thermische Verhalten von α-AlF3 detailliert zu beschreiben.

Резюме

Изучено термическое разложениеβ-AlF3 · ЗН2О, AlF3 · 3,5Н2О, AlF3 · 1,5Н2О,β-AlF3 и оксифторидов алюмин ия. Литературные данн ые были дополнены данными ре нтгенофазового анализа. Описаны перв ые стадии разложения этих соединений. Гидраты ф торида алюминия и оксифториды алюмини я были использованы в качестве модельных соединени й для детальной интерпретации терми ческого поведения а-А lF3.
