제목 Reaction kinetics for the preparation of LaMnO3 powder by means of self-propagating reaction
초록 LaMnO3 has been recognized as the host material for the solid oxide fuel cells (SOFC) which exhibited their potential use as clean and efficient powder-generating devices. The reaction for the preparation of LaMnO3 powder was analyzed by using TGA to predict the preparation kinetics. The extremely rapid weight loss giving rise to a very sharp exothermicity indicated that the reaction for the preparation of LaMnO3 powder from the precursors with Citric acid was the self-propagating reaction. The reaction order, activation energy during the non-isothermal reaction were predicted by adopting the Friedman, Ozawa-Flynn-wall and Vyazovkin methods. The optimum ratio of C/N was 0.8 for the optimum performance of the self-propagating auto-ignition reaction to prepare LaMnO3 powder within this experimental condition.
