Optimal Iron Oxides for Obtaining Hexaferrites
Presently, the ferrites industry consumes large amounts of iron osides obtained by spray roasting of steel pickling liquors. The aim of this paper is to propose the synthesis of optimal iron osidcs by oxyprecipitation of steel pickling liquors in order to obtain Bahexafenite wit11 high magnetic properties using the ceramic process. As a raw material. i t was used sulphuric liqoors with iron con...
متن کاملThe effective parameters on thermal recovery and reduction of iron oxides in EAF slag
Steelmaking slag of Mobarakeh Steel Company (MSC) has a high iron content which makes it unsuitable for conventional slag recovery; as in cement industries. On the other hand, EAF slag in this company is almost free of zinc because of using more than 90 percent DRI in the charge. Therefore, removal or recovery of iron from the slag can be a suitable solution to slag recovery in this company. In...
متن کاملThe Irony of Iron – Biogenic Iron Oxides as an Iron Source to the Ocean
Primary productivity in at least a third of the sunlit open ocean is thought to be iron-limited. Primary sources of dissolved iron (dFe) to the ocean are hydrothermal venting, flux from the sediments along continental margins, and airborne dust. This article provides a general review of sources of hydrothermal and sedimentary iron to the ocean, and speculates upon the role that iron-cycling mic...
متن کاملStructure and magnetism in ultrathin iron oxides characterized by low energy electron microscopy.
We have grown epitaxial films a few atomic layers thick of iron oxides on ruthenium. We characterize the growth by low energy electron microscopy. Using selected-area diffraction and intensity-versus-voltage spectroscopy, we detect two distinct phases which are assigned as wüstite and magnetite. Spin-polarized low energy electron microscopy reveals magnetic domain patterns in the magnetite phas...
