A two-dimensional finite element model is developed to study the
reaction kinetics and heat transfer during the self-propagating
high-temperature synthesis of La0.6Sr0.4MnO3,
a cathode and interconnect material used in solid oxide fuel cells. The
activation energy of La0.6Sr0.4MnO3
formation was calculated from experimental temperature history. The
calculated spatial-temporal temperature profile, heat generation rate,
reaction conversion, and flow pattern of surrounding gas during the
reaction are reported in this work. Hot spots are found at the corner
near the ignition point shortly after the ignition. The model provided a
simple and reliable way to design a large-scale production of La0.6Sr0.4MnO3.
