pulverization of iron
Redox cycling of iron/iron oxide has many potential applications for gas-phase reactions and electrochemical devices, including intermediate temperature (550-800 C) iron-air batteries [2,3]. The major limitation to such technologies is the pulverization and sintering of the iron substrate with repeated phase transformation-induced volume ...

Influence Of Redox Pretreatment On The Pulverization Of
Oct 01, 2015 The reduced ilmenite exhibited a serious pulverization problem, and its mean particle size decreased to less than 20 μm after leaching for 8 h. However, the ability to resist pulverization was retained after the weak reduction at 873 K, and the pre-treated ilmenite maintained their primary particle sizes during stirred leaching. The results of the preliminary experiment on the leaching kinetics for the …

Mesoporous Iron Oxide Directly Anchored On A Graphene
A continuous mesoporous iron oxide nanofilm was directly formed on graphene nanosheets through the in situ thermal decomposition of Fe(NO 3) 3 9H 2 O and was anchored tightly on the graphene surface. The lithiation-induced strain was naturally accommodated, owing to the constraint effect of graphene and the mesoporous structure. Hence, the pulverization of the iron oxide nanofilm was ...
