Investigation of the thermal dehydration of various modifications of CaSO 3 · 1 2 H 2 O using thermogravimetry and differential thermal analysis showed that different crystalline phases of anhydrous CaSO 3 are obtained. Differences in dehydration mechanisms which lead to these different crystalline structures, are due not only to the nature of the hemihydrate, but also to the conditions, e.g. water vapour pressure
摘要 使用热重法和差热分析法对CaSO 3 · 1 2 H 2 O 的各种变体的热脱水进行研究表明,获得了不同的无水CaSO 3 晶相。导致这些不同晶体结构的脱水机制的差异不仅是由于半水合物的性质,而且是由于进行脱水的条件,例如水蒸气压。
