India as a hot corrosion-resistant stabilizer for zirconia. (Reannouncement with new availability information)

OSTI ID:177481
India (In2O3)-stabilized zirconia (ISZ) plasma spray powder was prepared by a ManLabs proprietary sol-gel process, and evaluated for thermal stability and reaction/destabilization resistance to molten NaVO3-V2O5 mixtures at 700 deg and 900 deg C. The ISZ powder was superior to a fused-and-crushed commercial yttria-stabilized zirconia (YSZ) in vanadate resistance at 700 deg C and essentially equivalent at 900 deg C Some evidence was found to suggest that In2O3 has a strong positive deviation from ideal solution behavior in the ZrO2 matrix, which works to reduce the ultimate resistance of ISZ to corrosion/destabilization by vanadate melts.
