摘要：

Sol-gel prepared plasma spray powders of Sc2O3,Y2O3-stabilized ZrO2 (SYSZ), where the total amount of stabilizer is similar to 7 mol.%. and the stabilizer contains 2.5-20% Y2O3, have been found to give significantly better tetragonal (t') phase stability at 1400 degrees C than present-day Y2O3-stabilized ZrO2 thermal barrier coating (TBC) material. The results are discussed in the context of the ongoing effort to develop ZrO2-based (or other) ceramics suitable for ultra-high temperature TBC usage.
