Rare earth oxides co-doped zirconia has been developed for application in thermal barrier coating (TBC) systems to promote the performance and durability. In this paper, the phase stability and thermal physical properties of 1mol.%La2O3, 4.5mol.%Y2O3stabilized ZrO2(LaYSZ) were investigated. After 100 h heat treated at 1400°C, the content of monoclinic phase in LaYSZ was 2.32 mol%, which is lower than that in YSZ (46.9 mol%). Result indicates that the LaYSZ has better phase stability and lower thermal conductivity than YSZ. The LaYSZ system can be explored as the candidate material as ceramic layer in TBC.
