Properties of oxygen convertor slag as anticorrosive pigment

Abstract

The purpose of this work was to investigate the possibilities for the exploitation of the powder by‐product of oxygen convertor slag from the ferronickel industry as pigment in anticorrosive non‐toxic paints. The chemical composition of the powder shows a large content of Fe₃O₄ and a high value of pH, two features favouring its use in anticorrosive paints. Paints with this powder, either unrefined or processed, as a pigment and chlorinated rubber resin were produced and tested by the following methods: half‐cell potential, mass loss, chloride diffusion and EIS. The results indicated that protection of steel was achieved to a satisfactory level, especially with the processed material.
