| Abstract: | LiMn 2O 4 samples are prepared by heating a mixture of Li 2CO 3, MnCO 3 and C 6H 6O 7H 2O or a mixture of Li 2CO 3, MnCO 3 and H 2C 2O 4·2H 2O in air at 550～750℃ for 6h～10h. Their structure and chemical performance are studied using X-ray diffraciton, TG/DTA and TEM. It has been found that then reaction temperature is at 650℃ for 6h, a well ordered spinel LiMn 2O 4 stucture is produced. Particle sizes of powder are about 40nm. |
