The thermoelectric properties of Mn and Ni substituted sintered magnetite (Mn2/3Ni1/3)xFe3-xO4 were investigated for x=0, 0.4, 0.8 and 1.2 in the temperature range 100-700°C. It was found that the grain boundary didn’t affect the electrical conduction notably in this material. The thermoelectric power factor increased with increasing the temperature for each x, and marked a maximum value of 1.31 μW/K2cm for x=0.4 at 700°C.
