锰粉在水溶液中球磨生成相的研究
Phases Formed during Ball-milling Process of Manganese Powders
摘 要
使用高能行星式球磨机,在不同水溶液中球磨了金属锰粉末,通过XRD和TEM对生成相种类及其形貌进行研究.结果表明:球磨一段时间后,在机械力作用下,锰与水反应并获得了粒径为30～100nm的γ-Mn3O4;继续球磨,γ-Mn3O4进一步氧化或发生晶型转变;而且加入微量HCl和MnSO4极大地加快了反应速度,而加入微量NaOH则抑制了反应速度,并用Mn-H2O的电位-pH图对这些现象进行了解释.

Abstract
Manganese powders were ball-milled within water by high-energy planetary ball mill.The phases and morphology of as-formed powders were studied by XRD and TEM.The chemical reaction between the manganese powders and water occurred during the ball milling processing,and the γ-Mn3O4 nanoparticles with the size between 30nm and 100nm were prepared,which were further oxidized or transformed into another type of crystalline during the following milling processing.The chemical reaction rate increased when a little amount of HCl or MnSO4 was added into the solution but decreased when NaOH was added,which could be explained by Pourbaix diagram for Mn-H2O system.
