Solution Combustion Synthesis of LiMn2O4 with Different Starting Reactant Compositions

摘要：

　　Spinel LiMn2O4 powders were prepared by solution combustion synthesis using nitrate and acetate salts as raw materials and urea as fuel.The phase composition of as-synthesized powders was identified by XRD and the microscopic structure was examined by SEM.Single-phase spinel LiMn2O4 was prepared when acetate salts were used,and the incorporation of nitrate salts resulted in the formation of Mn2O3.The products consisted of slight agglomerations of fine particles with the size of 50-200nm.It was found that the addition of nitrate salts increased the reaction rate and the yield of LiMn2O4 was depressed when more nitrate salts were used as a reactant.
