由0.2mol-1Fe3+采用微波诱导加热制备了纳米尺寸的准立方形和纺锤形-Fe2O3粒子, 与常规加热方式比较微波加热制得的-Fe2O3粒子粒径小且分布均匀, 实验证明无机离子加H+、OH-和Na+等的加入可明显加速反应速率.
Nanometer-sized quasicubic and spindle -Fe2O3 particles were prepared by microwave heating from 0.2mol-1Fe3+ salts solution. The obtained -Fe2O3 particles have smaller sizes and uniform distribution by contrast with conventional heating. Inorganic ions such as H+, OH- and Na+, can obviously affect the precipitating rate of spindle -Fe2O3 and accelerate the hydrolysis of ferric ions.
