摘要
本文研究了Fe(NO3)3-NaH2PO4体系水解合成纺锤形α-Fe2O3微晶的动力学过程。通过使用似稳定浓度法,根据动力学曲线确定了成核阶段的速率方程,计算了成核过程的活化能,从动力学角度解释了α-Fe2O3微晶的形成机理。
おhe kinetic process of synthesis spindle αFe_2O_3 by hydrolysis of Fe(NO_3)_3NaH_2PO_4 system was conducted.The rate equation of nucleation was given by quasistable concentration on the basis of kinetic curves.Activation energy of nucleation was calculated.The formation mechanism of αFe2O3 fine crystal was explained from kinetic point of view.
