LiMn2O4的湿法合成及锰的光度法测定研究
无机化学学报,2003,19(5):552~556,-0001,():
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(Ⅲ) and Mn (Ⅳ) of LiMn2O4 spinel were determined simultaneously by spectrophotometric analysis with pyrophosphoric acid.
