Method for synthesizing hercynite through molten salt electrolysis
The invention belongs to the technical field of ceramic materials, and provides a method for synthesizing hercynite through molten salt electrolysis. According to the method, a cathode piece made of Fe2O3 powder and Al2O3 powder is electrolyzed through a molten salt system, Fe2O3 is electrolyzed into FeO under the action of an electric field, then power is cut off, temperature is increased, FeO and Al2O3 react to synthesize FeAl2O4, and since FeO and Al2O3 are combined to form FeAl2O4 in molten salt, the interface bonding capacity between FeO and Al2O3 is enhanced. The result of the embodiment shows that FeAl2O4 prepared by the method provided by the invention is high in crystallization degree and good in crystal form.
本发明属于陶瓷材料技术领域，提供了一种熔盐电解合成铁铝尖晶石的方法。本发明通过采用熔盐体系电解由Fe2O3粉和Al2O3粉制成的阴极片，在电场作用下使Fe2O3电解为FeO，再断电升温使FeO与Al2O3发生反应合成FeAl2O4，由于FeO与Al2O3结合形成FeAl2O4是在熔盐中进行，增强了FeO与Al2O3之间的界面结合能力。实施例的结果显示，采用本发明提供的方法制备得到的FeAl2O4结晶程度高、晶型好。
