Solid Nano Ferrite Embeddable Reference Electrode for Corrosion Monitoring in Reinforced Concrete Structures

In this paper, nano NiFe2O4 and CoFe2O4 was prepared by simple metal chloride precipitation method and the prepared sample was characterized using X- ray diffraction and FTIR. XRD pattern reveal the formation of cubic spinel phase of the prepared sample and the average crystalline size was found to be less than 60 nm. A solid state reference electrode has been fabricated by MFe2O4 and its suitability for using it as a potential sensor in high alkaline medium was analyzed by reversibility and polarization studies. The studies proved that the sensor is highly stable in alkaline environment and can be used as an embeddable sensor for corrosion monitoring of reinforced concrete structures.
