Synthesis of LiMn2O4 and LiCr0.2Mn1.8O4 powders by modified Pechini process

open access: yesSemina: Ciências Exatas e Tecnológicas, 2009
LiMn2O4 and LiCr0.2Mn1.8O4 powders were synthesized by Pechini process, modified in order to reduce the number of steps and to work at temperatures below or equal to 400oC. Both phases crystallize in the same spinel structure with lattice constants of 8.
