摘要
本文按T.Takada提供的氧化铁微晶生成相图,分别讨论了针形和纺锤形α-FeOOH微晶及Fe_3O_4超微粉的生长机制。从实验结果来看,上述微粒子的形成过程均属“溶解-析出”机制。文中还简要介绍了这些微粉的应用。
A brief study and discussion on the growth mcchanism of iron oxides crystallites, the preparation condition and its application to inorganic dyestuffs and magnetic recording materials have been given. The result shown that the growth mechanisms of uniform needle or spindle α-FeOOH crystallites and cubic grain Fe_3O_4ultra-fine powder were about the same 'Solution-Deposition' processes.
