Add to ORKGA phase diagram is proposed for the system BaMnO_3-manganese oxide showing the phases which can exist in air at temperatures between 1,000 and 1,200℃. Five phases are observed : two layer BaMnO_3,fifteen layer BaMnO_3,a new compound BaMn_4O_7,tetragonal Mn_3O_4 and cubic Mn_3O_4. A compound BaMn_4O_7 decomposes into two layer BaMnO_3 and tetragonal Mn_3O_4 at 1,050℃
