Article.
Mater. Today Commun.. vol: 31. page: .
Date: JUN. 2022.
Doi: 10.1016/j.mtcomm.2022.103453.

Abstract:
BaMnO3 perovskite oxide is an interesting material for many high-temperature technological applications due to its facile reduction capacity at reasonably low temperature. The thermochemical properties of BaMnO3 largely determine this reduction behaviour at high temperature. However, the temperature-dependent thermochemical properties of [read more]
