| 摘 要： | 为进一步开发利用钛白石膏,利用XRD和DTG考察了钛白石膏的物相组成及其脱水性能。结果表明,钛白石膏的主要成份是二水石膏,杂质主要是铁、铝、镁、钛、硅,其中含量最高的铁主要以Fe2O3存在。钛白石膏的脱水反应发生在115℃～152℃,脱水机理与化学石膏的脱水机理相似,只是脱水峰温较化学石膏的略高。

| Abstract: | The phase composition and dewatering characteristics of titanium gypsum were studied by XRD and DTG for development and utilization.The results show that the main content is dehydrate gypsum and main impurities is iron,aluminum,magnesium,titanium,silicon in titanium gypsum.Iron is the highest impurities and existed in Fe2O3 in titanium gypsum.The dewatering reaction happens at 115℃～152℃,and the reaction mechanism is similar as chemical gypsum,but dewatering temperature is slightly than chemical gypsum. |
