摘　　要：从化学成分、物相构成及微观结构方面系统研究了冷态熔盐体系的构成,发现冷态熔盐体系中物相以TiO2、SiO2及氯化物熔盐和钙铁氧化物复合体存在;熔盐体系在冷态条件下发生结块现象,表观形貌凸凹不平,呈现疏松状;通过系统取样分析,研究了重要组分在熔盐氯化炉熔盐体系中的纵向、横向分布情况,结果表明:TiO2、SiO2、Al2O3在熔盐体系纵向切面从上到下基本呈现递增趋势,C、FeCl2、FeCl3含量在熔盐体系中从上到下逐渐递减,在横向截面上大多组分没有呈现出明显规律。The chemical compositions,phase structures and microstructures of cold molten salt are studied. It is found that the molten salt system exists in complexus of TiO2,SiO2,chloride molten salt,calcium oxides and iron oxides. Molten salt system agglomerates under cold condition with uneven appearance and loose state. The longitudinal and transverse distributions of important components in the molten salt are researched by systematic sampling. The results show that at longitudinal section,the contents of TiO2,SiO2 and Al2O3 increase gradually from top to bottom,and the contents of C,FeCl2 and FeCl3 decrease gradually from top to bottom while most of the components at transverse section do not show a apparent rule.
