Magnetite is a natural iron oxide magnet Our black iron powder products have 98 or Fe3O4 Magnetite 99 Fe3O4 (Black Iron Oxide) It occurs in crystals of the cubic system in masses and as a loose sand It is one of the important ores of iron (magnetic iron ore) and is a common constituent of igneous and metamorphic rocks Black iron powder is also used as a colorant for a wide.
May 10 2021 Hematite ore was partially reduced to suboxides in the specified atmospheres Accorading to the thermodynamic analysis [14 15] these suboxides contained magnetite and liquid oxide and the liquid oxide turned to w stite in the quenching process The partially reduced ore particles in resin were polished and investigated with an optical microscope.
