Magnetite is an important material component of power plants as it is used to generate electricity. Magnetite, owing to its magnetic properties, is widely used in compasses and other navigation devices. Magnetite also serves as an excellent abrasive which is a cleaner and has way lower toxicity than abrasives that have a silica base.
Sep 23, 2006 Abstract. The reactions of ammonium hydrogen fluoride with three oxides of iron, viz., a-Fe 2 O 3, Fe 3 O 4 magnetite and -Fe 2 O 3 maghemite in the solid state at room temperature and at slightly higher than the ambient have been studied. The products were characterised by powder XRD, TGDTA, chemical analysis and M ssbauer techniques.
