    Identification Of Magnetite And Hematite In Rocks By

    The memory of room-temperature magnetization has been described previously for hematite and magnetite. It has also been found that under the conditions of the present experiments there is a reciprocal relationship across the transition temperature between the low- and ordinary-temperature IRM of magnetite.

    Hematite also has a high intensity band in the high wavenumber region. Because magnetite does not have Raman scattering in this wavenumber region, this Raman response can be used to distinguish these two oxides. The 1320 cm -1 band changes with changing magnetitehematite ratios are presented in figure 3. Figure 3.

    Metal Oxides In Soils The Effects Of Hematite And Magnetite

    Like magnetite, hematite is an oxide of iron and it has the formula Fe 2 O 3. Hematite is not magnetic, and so is not readily removed from soils to which it has been added. It also can occur naturally in soil. Hematite is the most prevalent oxide of iron present in the ground, as such, it is also the largest source of iron for ironsteel ...

    The transformation of magnetite to hematite occurs along 111 planes, and results in the development of hematite domains along 111 that are parallel to the foliation. The difference in volume created by the transformation of magnetite to hematite and the shear stress acting on the interphase boundaries allow fluids to migrate along these planes.
