Nano-crystalline CoFe2O4 particles were synthesized through thermal 
decomposition of cobalt tartrate- ferric tartrate at 250, 450, 750 and 1050oC. 
The samples were characterized by XRD, DSC-TG, SEM, TEM and FT-IR. 
The XRD analysis showed that the sample calcined at 1050 oC exhibit pure 
spinel phase. The crystallite sizes lie in the range of 30 – 61 nm. The samples 
obtained at different calcination temperatures have different morphologies. 
The kinetics of thermal decomposition of metal tartrate mixtures were studied 
using non-isothermal thermogravimetric techniques. The thermal 
decomposition proceeds in three steps for cobalt iron (III) tartrate. The kinetic
analysis of non-isothermal data of the decomposition reaction is best described 
by the Random nucleation in (three-dimentions) (A4) models. The activation 
parameters were calculated and the results of the dynamic integral methods 
were compared and discussed
