摘要
Concerning the generation of manganese ferrite by coprecipitation from MnO2 and FeSO4H2O aqueous solution, based on TG, DTG and DTA measurements, IR and mass spectra, SEM and X-ray diffraction data, the authors present an investigation on the elimination of water from the non-aged, aged and air-calcined coprecipitates. Some powders microstructure changes generated by water release through aging in solution or heating in air are presented. (C) 2001 Editions scientifiques et medicales Elsevier SAS.
