The complex polymerization method has enormous potential for obtaining magnetic ceramics, because it is a simple process, that originates from materials with high purity, which leads to obtaining powders with high chemical homogeneity and high surface area. This work aims to evaluate the structural and morphological characteristics of ferrites Ni0,25Zn0,75Fe2O4 and NiFe2O4 obtained by polymerization complex method. The solution was subjected to a final temperature of 120°C until the formation of the resin pyrolysed at a temperature of 350°C for 2 hours and calcined at 500°C for 2 hours. The resulting powders were characterized by X-ray diffraction (XRD), thermal analysis (TG/ DSC) and scanning electron microscopy (SEM). The results of XRD showed the formation of two compositions majority of ferrite phase. The results of SEM micrographs showed the formation of agglomerated particles with longitudinal plates to both compositions being important microstructural characteristics for magnetic application. The method of polymerization of complexes appeared as a promising method to obtain ceramic powders of nickel ferrite and nickel-zinc alloy for magnetic application.Article Structural refinement, growth mechanism, infrared/Raman spectroscopies and photoluminescence properties of PbMoO4 crystals(Elsevier, 2013-02-13) Delmonte, Maurício Roberto Bomio; Cavalcante, L.
