ABSTRACT
This paper presents the series of experiments performed for study and description of kinetics of non- or low-magnetic iron containing samples thermomagnetization in open air. It is shown that the kinetics of the thermomagnetization of pure hematite samples in the isothermal conditions (close to and above the hematite dissociation temperature) have sharply pronounced oscillating character. It is shown that the iron containing phases forming during this process can be stabilized by water hardening. The magnetic properties of hardened samples were studied. The Mossbauer studies of hardened samples allowed to compare the results of magnetic measurements with phase composition of hardened metastable state and to establish possible mechanism of oscillations observed. Investigations of electrical conductivity kinetics both by study of hardened samples and of the hematite samples in process of roasting showed good correlation with the magnetizatization kinetics. It may allow to combine methods of heating.
