A simple route to synthesize new binary cobalt iron cyclotetraphosphate CoFeP4O12 using aqueous and acetone media
A new binary cobalt iron cyclotetraphosphate, CoFeP4O12 was synthesized through solid phase reaction using cobalt carbonate, iron metal and phosphoric acid in the presence of water-acetone media with further calcinations at the temperature of 500 °C. The particle size obtained from X-ray line broade...
