Even when magnesiowustite is rapidly cooled in a reducing atmosphere, a small volume fraction of spinel forms. These results provide a basis for understanding the large discrepancies in M‐H curves and the observed quadrupole splitting in Moessbauer spectra reported by various workers. In addition, it is shown that, with modern monochromatic X‐ray diffraction techniques, a volume percent <0.10 can readily be measured.
