【摘要】 以矿卤滩晒副产物为原料,无水氯化镁为晶型助长剂,十二烷基硫酸钠为分散剂,研究了用水热法制备硫酸钙晶须的工艺影响因素。借助扫描电镜(SEM)和电子显微镜分析了硫酸钙晶须的形貌。用热重分析仪对硫酸钙晶须进行热重分析,并对产品进行了粒度分布测定。更多还原

【Abstract】 The process factors of preparation calcium sulfate dehydrate whisker by hydrothermal method was studied using by-product of bitter ore calcium sulfate as raw materials,magnesium chloride anhydrous for the crystal promoter,sodium dodecylsulfate as dispersant. The morphology of calcium sulfate whisker was analyzed by SEM and electron microscope. Thermogravimetric analysis was carried out on the calcium sulfate whisker via using thermal gravimetric analyzer and particle size distribution measurement of the product was determined.更多还原
