摘要
The LiMn2O4 spinel was prepared by wet method using Li2CO3, Mn(CH3COO)2·4H2O and CO2 as raw materials. The products were measured by TG/DTA, XRD, IR. The results Showed that the sample calcined at 800℃for 10h was well crystallized monophase product. The contents of Mn?and Mn?of LiMn2O4 spinel were determined simultaneously by spectrophotometric analysis with pyrophosphoric acid.

The results Showed that the sample calcined at 800degreesC for 10h was well crystallized monophase product. The contents of Mn(III) and Mn(IV) of LiMn2O4 spinel were determined simultaneously by spectrophotometric analysis with pyrophosphoric acid.
