| 摘 要： | 对半水硫酸钙晶须水化产物进行了形貌的实时、非实时观测和XRD分析.结果表明半水硫酸钙晶须水化过程的显著特点在于其晶型和形貌的改变及由此引起的长径比减小;半水硫酸钙晶须的水化过程包括3个阶段:半水硫酸钙晶须水化初始期,二水硫酸钙晶须生成期,二水硫酸钙晶须的粗化溶解及新的二水硫酸钙晶体生成期.半水硫酸钙晶须的水化过程与半水石膏的水化过程略有不同.

| Abstract: | Both real-time and out-of-time observations and XRD analysis were carried out for the products from the hydration process of hemihydrated calcium sulfate whiskers.The results indicated that the process is characterized mainly by the changes of crystalline form and morphology of whiskers and the reduction of whiskers' aspect ratio.Based on the observations it was found that the hydration process of hemihydrated calcium sulfate whiskers can be divided into three phases,i.e.,the initial hydration of hemihydrat... |
