SURVEY THE ELECTROCHEMICAL PROPERTIES OF THE MAGNETITE ANODE PREPARED BY POWDER METALLURGHY METHODS
The magnetite anodes prepared by powder metallurgy methods were tested in 3.5% NaCl solution; its characteristics such as current densities and anode dissolution rates were determined. The XRD, SEM and EDS data for analyzing of compositions and structure of materials were also presented. The recorded results of testing showed that, the inner magnetite anodes have high current densities and low dissolution rates, which satisfy the requirements of the using in the ICCPs systems.
