Samples were prepared from iron nitrate, iron sulfate and iron chloride and the thermal curves obtained were analyzed by specific area measurements, X-ray diffraction and Mössbauer spectroscopy. It was found that the iron oxyhydroxide precursors affect the temperatures of the hematite formation as well as the textural properties of the final hematite producing particles with different diameters as following: iron sulfate (3.3 nm)<<iron nitrate (15 nm)<iron chloride (24 nm).Submitted by Ana Valéria de Jesus Moura (anavaleria_131@hotmail.com) on 2011-12-16T12:04:48Z No. of bitstreams: 1 03 fulltext.pdf: 383738 bytes, checksum: 91a46dc54702b749a6a9f1be07b0c9ce (MD5)Made available in DSpace on 2011-12-16T12:04:48Z (GMT).
