抄録

The effect of grain size on the oxygen intake/release kinetics were investigated for double-perovskite type BaYMn₂O_5+δ (δ = 0.0–1.0). The preparation of BaYMn₂O_5+δ with larger specific surface area was achieved by low-temperature firing (down to 900°C) of precursors obtained from a wet-chemical route. The oxygen intake/release rates at 500°C were found to increase significantly in the resultant BaYMn₂O_5+δ fine powders, indicating a key role of the powder surface in the oxygen intake/release processes.
