Síntese e caracterização de cobaltita de níquel (NiCo2O4) obtida pelométodo dos precursorespoliméricos

Abstract: RESUMO A cobaltita de níquel (NiCo2O4) de estrutura do tipo espinélio apresenta baixa estabilidade térmica em torno dos 400 °C, que ocasiona a perda de NiO, afetando de maneira significativa as propriedades físicas e estruturais do material produzido. Neste trabalho a cobaltita de níquel foi preparada pelo método dos precursores poliméricos. O material foi calcinado a 350 °C e tratado termicamente nas temperaturas entre 450 – 650 °C. O produto obtido foi caracterizado por Termogravimetria e Calorimetria Explor… Show more
