Abstract:
Oxalates of Cu2+, Mg2+, Zn2+ and Fe2+ were coprecipitated from the mixture of respective acetate solutions using 0.6 M oxalic acid solution to form a homogeneous solid solution MgxCu(0.5-x)Zn0.5Fe2 (C2O4)(3). nH(2)O With x=0.00, 0.20, 0.25 and 0.40. To determine ferritization (formation of ferrite) temperature of resulting ferrite system, MgxCu(0.5-x)Zn0.5Fe2O4 With x=0.00, 0,20, 0.25 and 0.40, TG/DTG/DTA studies (STA) were carried out on coprecipitated oxalate complexes, These studies revealed the low ferritization temperature (326 degrees-370 degrees C) of the ferrite system and occurrence of simultaneous decomposition and ferritization processes. The ferrite system was characterized using X-ray diffraction study, which revealed the presence of single spinel phase.
