Phase equilibria in the system Pr+Co+O at 1100 and 11503C are established by changing the oxygen partial pressure from 0 to 12.00 in ؊log (P O 2 /atm), and a representative phase diagram at 11003C is presented for the Pr 2 O 3 +Co+CO 2 O 3 system. Under experimental conditions, the PrO 1.63؉ ( ), Pr
