摘要：

Lowering the thermal conductivity of thermal barrier coatings used to protect blade and vane airfoils represents an important challenge for gas turbine designers and manufacturers. Dense zirconia-based materials have been prepared by solid state reaction methods to determine their thermal properties up to 1000degreesC. Partially stabilised zirconias having a thermal conductivity 40% lower than the thermal conductivity of the most widely used system (ZrO2-8wt.%Y2O3) have been obtained.
