摘要
本文研究了煅烧硬石膏的结构及硬石膏的高温相变。发现不同温度煅烧的硬石膏晶体结构及显微形态是相同的，仅存在不同程度的晶格畸变和晶粒尺寸的差异。硬石膏的高温相变是可逆相变，二者的转变温度略有差异。
The structure of calcined anhydride and its phase transition at high temperature havebeen studied in this paper. It is found that there is no difference in crystal structure and microscop-ic image of calcined anhydride, but a varying degree of lattice distortion and a difference in grainsize are noticed at different temperatures. The high-temperature phase transition of anhydride is areversible one, the phase transition temperatures at heating and cooling are somewhat different.
