| Abstract: | The spherical NH_4FePO_4 powders were synthesized by a controlled crystallization process using ammo- nium citrate as the complexing agent.Morphology and distribution of the spherical NH_4FePO_4 powders were observed by scanning electron microscopy (SEM).The effects of the loading methods,reaction temperature, speed of dripping,agitating rates and reactant concentration on the appearance of NH_4FePO_4 powders were studied and the most efficient process for preparing spherical NH_4FePO_4 powders was determined. |
