摘要：

A new cubic perovskite compound BaLaMgMnO6-x has been prepared under high temperature (900°C) and high oxygen pressure (60-70 kbar) using in situ thermal decomposition of KClO3 in a belt apparatus. X-Ray diffraction (XRD), redox titration, thermogravimetric analysis (TGA), and X-ray photoelectron (XPE) spectroscopy investigation have shown that x is close to 0.21 under these synthetic conditions. Mn(V) in octahedral coordination could be postulated. © 1990.
