They concluded that magnetite goes through two stages of oxida-tion on being heated in air, the first stage being a surface oxidation to hematite and the second stage a complete oxidation also to hematite. They state that formation of gamma-FezO3 was not detected at any stage. The writer (7) independently studied the oxidation of magnetite by

Aug 07, 2014 · Thermogravimetric analysis (TGA) of magnetite (Fe3O4) oxidation was conducted at temperatures ranging from 750 to 900 °C over 10 oxidation cycles. Oxidation experiments were carried out in a continuous stream of air for period of 30 min. The oxidized magnetite (Fe3O4), which resulted in formation of hematite (Fe2O3), was then reduced by using continuous stream of CO (5% and 10%) .
