中和沉淀法Fe_3O_4的生成过程研究

Study On Fe_3O_4 Formation Processing By Neutral Precipitation

本文利用XRD等技术对中和沉淀法Fe3O4的生成条件进行了研究,得到了Fe3O4的生成条件图。并以此对中和沉淀法Fe3O4的生成过程进行了讨论,发现Fe3O4的生成过程和空气氧化法Fe3O4的生成过程截然不同。中和沉淀法Fe3O4的生成过程随R及反应PH的不同而不同。反应温度的提高有利于Fe3O4生成量的增加并使Fe3O4的生成条件区域扩大。

Study on Fe3O4 formation condition in neutral precipition processing by CRD technique and the Fe3O4 formation condition graph in given is this paper.On this account to discuss the forma tion machnism of Fe3O4 in neutral precipitation processing. It is found found tbat the formation mach nism in neutral precipitation processing is different from ,it in air oxidata processing ,Formation machnism in neutral precipitation processing is changed with and PH.With the temperature go UP the Fe3O4 formation quantily in creased and the formation condition area of Fe3O4 expanded.
