NEW METHOD OF SYNTHESIS OF NANOSIZE POWDERS OF CoFe<sub>2</sub>0<sub>4</sub>
The new method of synthesis of cobalt ferrite powders has been considered and the conditions of the process were determined. In this process the strongly basic anion exchange resin AB-17-8 in hydroxide form was used and coprecipitation of cobalt and ferric ions in the insoluble compound was occurred. The obtained product was studied by transmission electron microscopy and X-ray phase analysis. It was found that the product is a pure phase of CoFe<sub>2</sub>0<sub>4</sub> and consists of octahedral particles with a size from 70 to 90 nm.
