with thermodynamic descriptions of Ce-O and La-O systems from literature, several property diagrams of Ce-La-O system were calculated and used to explain oxidation process of the Ce-La alloys. The fluorite phase is the unique oxidation products for most of the Ce-La alloys. Key words: Ce-La alloy; phase diagram; thermodynamics; oxidation 1 Introduction During past few years, attention has been paid......
