Abstract:Zinc-ferrite pigment was prepared by solid-state reaction. A mixture of a-Fe2O3 and ZnO in a molar ratio of 1:1 was fired at 1,200°C. X-ray diffraction measurements proved that the reacted material crystallized into a spinal structure. Measurement of the pigment specification and properties were carried out according to standard international methods. The pigment extract and the extract of the pigment-linseed oil mixture were examined for use in protecting steel panels against rust. The prepared pigment was incorporated in some paint formulations. Physical, chemical and mechanical properties of the formulated paint films were studied and also tested for corrosion resistance. Finds that zinc ferrite is a basic pigment and can be recommended for use in anti-corrosive paints. High corrosion-resistant coatings can be obtained by incorporating zinc-ferrite pigment in organic coating systems that cannot saponify; protection increases as the pigment-binder ratio increases. Chemically follows up and physically emphasizes the mechanism of corrosion protection by the use of a Mossbauer spectroscope.
