Hexagonal ferrites with M, Y and W structures were prepared from powders obtained by the decomposition of organometallic salt (citrate) solidified solutions, Due to the improved reactivity of these powders with respect to the classical ceramic ones, a number of advantages were obtained: pure hexaferrites were produced at lower temperature; they exhibited improved magnetization and coercitivity; a finer and more homogeneous granulometry was achieved in the final products. X-Ray diffractometry, magnetic analysis and SEM microscope observations were used for characterizing the obtained materials.
