Abstract
Formation of iron oxide powders by spray-pyrolysis technique from the ethanol solution of several Fe salts, mainly of nitrates, was investigated to elucidate the effects of reaction conditions on the properties of products. The reaction was carried out by spraying . the solution into a reactor heated by an electric furnace.α-Fe2O3 powders obtained from Fe nitrate at 600°-1200°C became finer and less porous withincreasing reaction temperature. The particles were finer than 1μ at 1200°C. By changing the solution to air ratio, one can obtain the iron oxide powders which are composed mainly of α-Fe2O3, γ-Fe2O3, and Fe2O4 or FeO. The kind of iron salt gave a considerable effect on the shape and size of iron oxide particles produced: The oxalate and lactate gave hollow particles of α-Fe2O3.
