Abstract

LiMn₂O₄ and LiCr_0.2Mn_1.8O₄ powders were synthesized by Pechini process, modified in order to reduce the number of steps and to work at temperatures below or equal to 400^oC. Both phases crystallize in the same spinel structure with lattice constants of 8.21 and 8.22 Å respectively. Although the annealing temperature was low, the cristallinity is good and no residual amounts of organic material were detected.
