Li2MnO3 Synthesis by Citrate Sol-Gel Method and Electric Property

Abstract

Abstract: Li₂MnO₃ ultrafine powders were synthesized by the citrate sol-gel method using Li₂CO₃,
MnCO₃ as raw materials. The powder samples were characterized by DTA, TG, XRD and TEM. Ionic conductivity of the sinter was determined by
means of A-C impedance technique. The experiment results show that Li₂MnO₃ pure phase is formed at over 650℃. The diameter of the powder is below
50nm. The measured magnitudes of conductivities are in the range of 10^-6～10^-3s·cm^-1, the value of activation energy
is 44.87kJ·mol^-1 from 18℃ to 400℃.

Key words: Li₂MnO₃, ultrafines, citrate Sol-Gel, ionic conductivity
