Influência do tratamento térmico nas propriedades estruturais e microestruturais de ferrita de níquel obtidas por métodos de combustão.

Abstract

Nickel ferrite spinels are ceramic compounds of important application. in electronic devices, electromagnetic materials and catalysis, in light of this, to elucidate the structural and microstructural properties of the powders obtained by the normal reaction route of combustion. The proposal developed by the authors is to calcine at 600ºC, 800ºC and 1000ºC, two samples by batch and after the end of the firing abruptly remove one of the samples and characterize both by X-ray diffraction (XRD), right after the refinement of the samples through the Rietveld method to obtain some microstructural properties. The X-ray diffraction results will show that the proposed phase has been formed and what will be the that phase. Subsequently, the refinement study will allow know the quantification of the phases parameters, lattice size, crystallite size and micro deformation. The present This research contributes to the scientific development of the student and gives the chance to learn about the X-ray diffraction analysis technique and its applications in nickel ferrite
