Ca 0.5 Na 0.5 Cu 2.5 Mn 4.5 O 12 , CaCu 3ุx Mn 4ุx O 12 (0.54x42) were prepared at 7003C and 2600 PSI by combined sol+gel and high oxygen pressure methods. CaCu 0.5 Mn 6.5 O 12 and CaMn 7 O 12 (xโซ5.2ุโฌ and 3) were prepared by solid state reactions in evacuated quartz tubes at 9003C. These compounds
