利用沸腾回流强迫水解法由FeCl3或Fe(NO3) 3溶液( 0 .5 -1.0mol·L-1)在弱酸性环境下 ,制备了均匀亚微米级α -Fe2 O3胶粒。如果在反应液中加入微量Na2 SO3,完全转化为α-Fe2 O3粒子的时间可缩短至几小时。使用XRD和TEM对产品的物相及形貌进行了表征
The homogeneous submicron α -Fe 2 O 3 colloidal particles were prepared by boiling reflux forced hydrolysis method from FeCl 3 or Fe (NO 3) 3 solution (0.5-1.0 mol·L -1) in weak acid environment. If a small amount of Na2 SO3 is added to the reaction solution, the time for complete conversion into α-Fe2O3 particles can be shortened to several hours. The phase and morphology of the product were characterized by XRD and TEM
