The mass of the magnetite sample was 10 mg in all experiments. Before kinetics studies, magnetite samples were calcined with Ar flow 10 cm 3 s −1 at linear heating of 10 °C min −1 to the temperature of 600 °C in the external magnetic field of 60 Oe. For further research, hydrogen (99.993%) was used without preliminary purification.Magnetite. Nanomagnetite, Fe3O4, is also used in the development of electrochemical (bio) sensors [26,27] due to having as main characteristic high electron transfer rate, functional groups on their surface that allow functionalization with other species, in addition, to present magnetic properties, which, in the presence of a magnet, helps in the better distribution of nanomaterials on the ...Magnetite - an overview | ScienceDirect Topicsmagnetite, iron oxide mineral (FeFe 2 O 4, or Fe 3 O 4) that is the chief member of one of the series of the spinel (q.v.) group.Minerals in this series form black to brownish, metallic, moderately hard octahedrons and masses in igneous and metamorphic rocks and in granite pegmatites, stony meteorites, and high-temperature sulfide veins.
