摘要
本文对钙矾石晶体脱水研究,发现钙矾石晶结构中存在有七种结构水,它们分阶段脱去,改变着晶体的结构。特别是B类OH水脱去,X射线衍射显示为无定形结构,各国学者认定属无定形物质,通过再水合分析,认为无水的钙矾石仍保持有介稳准有序结构。
In studying the dehydration of ettringite, it is found that there are seven kinds of structural water which dehydrate separately at different stages of dehydration .This causes the change of crystal structure of Ettringite.In particular, for the dehydration of 'OH water of B kind', Xray diffraction shows the substance to be amorphous.Many foreign scholars consider the substance amorphous. However, by rehydration process, it is ascertained the Ettringite still holds the boundary-stable quasi-ordered structure.
