Abstract The authors analyse the possibility of obtaining manganese-zinc ferrite through the transformations of polynuclear coordination compounds (pcc), either in the solid state or in a reaction medium. Polynuclear coordination compound precursors with the general molecular formula: [Fe(II)xFe(III)y(Mn0.5Zn0.5)(C2O4)2(OH)y+2(H2O)2] with 0.2〈x〈1.0, 1.0〈y〈1.8 and x+y=2, obtained through a forced hydrolysis were characterized by chemical and physicochemical procedures. A non-isothermal kinetic analysis of the thermal decomposition steps showed that all of them are described by contracting geometry rate equation. The influence of the thermal treatment on the properties of the final products of transformation was evidenced.
