Composition of Hydration Products
The Journal of the Society of Chemical Industry, Japan, 1964 前報では,種々の水和反応温度でそれぞれの水和過程および水和生成物,水和物をX線回折,熱天秤分析および化学分析によって調べた結果を報告した。本報では,X線回折,示差熱分析および赤外線吸収スペクトルなどの手段によって完全水和生成物,完全水和物試料の組成につき検討を試みた。そこで, 50,80および100℃の水和反応で得られた試料につきX 線回折図の変化を検討し, さらに示差熱分析によって加熱変化の機構を調べた。一方,完全水和物が新しい結晶性の物質であるとの知見を得るため,赤外吸収スペクトルの測定を行なった。その結果,完全水和物は新しい化合物で結晶性の物質であることが明らかになった。また加熱による脱水反応から相変化を容易に生じ新しい結晶構造を示すことを知った。なお ...
