摘要
测定了煅烧硬石膏的溶解度及其相关性能 ,发现不同温度煅烧的硬石膏具有不同的溶解度 ,5 0 0℃左右煅烧的硬石膏具有最大的溶解度。通过采用 XRD对其特定衍射线进行精细结构测定 ,发现不同温度煅烧的硬石膏会有不同程度的结构畸变 ,5 0 0℃左右煅烧的硬石膏晶格结构变化最为明显 。
The solubility and the related properties of calcined anhydrite were determined. It is found that there is different solubility of calcined anhydrite at different temperature and the highest at 500℃.There are different structure distortion of calcined anhydrite with the changes of temperature and the most obvious at 500℃ .It is pointed out that the main reason for solubility change is structural distortion of calcined anhydrite , which determined by XRD and vicom image analysis.
