| Abstract: | Summary Phase, structural and magnetic changes, occurring under oxidation and at increased temperatures, are studied on four samples of magnetic fractions. The samples of magnetic fractions, containing titanomagnetites at different oxidation levels, were oxidized at a temperature of 400°C for 1, 60 and 300 mins. With the aid of X-rays and Mössbauer's spectrometry it has been proved that under oxidation non-stoichiometric titanomagnetites and titanomagnetites plus ilmenite and pseudobrookite are formed. |
