The method includes the steps of mixing barium nitrate (Ba(NO3)2), cobalt nitrate hexahydrate (Co(NO3)2·6H2O), and ferric nitrate nanohydrate (Fe(NO3)3·9H2O) at the ratio of 3:2:24 to form a liquid phase mixture, co-precipitating the mixture using sodium hydroxide to metallize the mixture, washing and drying the co-precipitated mixture, heat-treating the washed and dried mixture, and adding aluminum oxide (Al2O3) to the mixture.
