均分散纺锤形α-Fe2O3的制备研究
A STUDY OF THE PREPARATION OF MONODISPERSED SPINDLE HEMATITE
【摘要】 用沸腾回流的强迫水解法制备了纺锤形均一的α-Fe2O3粒子.系统地研究了不同晶体助长剂及浓度对沉淀粒子晶貌的影响,用TEM和XRD对粒子的形态和组成进行了表征.讨论了均匀纺锤形α-Fe2O3粒子的形成机理.
【Abstract】 The spindle monodispersed hematite particles were prepared by forced hy drolysis in boiling refluex state from Fe(NO3)3 solution for 70h. The influcence of modifers and their concentration on the size and morphology of the particles were studied.The morphology and composition were characterized by TEM and XRD. The mechanism of formation of spindle α - Fe2O3 was discussed.
