Influence of gadolinia on thermal expansion property of ZrO2–4.5mol%Y2O3 ceramics

Effects of Y2O3 addition on the phase evolution and thermophysical properties of lanthanum zirconate

“…It is important to note that there are some structural features (e.g., defects such as oxygen vacancy V ö , substitution cation Y 3+ and other imperfections in the lattice such as pores or varying properties in thermal expansion along with different orientations) that have a significant effect on the overall TECs of different La 2 O 3 -ZrO 2 -Y 2 O 3 ceramics [23,24].…”

Coprecipitation synthesis and thermal conductivity of La2Zr2O7

“…Hot section components working in the combustion system must meet the rigorous requirements for extreme conditions, such as high temperature, thermal stress, thermal shock and severe corrosion [1][2][3][4]. The application of thermal barrier coatings (TBCs) can result in a large temperature decrease between the hot gas and the metal substrate.…”

Thermophysical properties of lanthanum zirconate coating prepared by plasma spraying and the influence of post-annealing

“…Besides, an optimized powder source can also improve the thermophysical properties of the coating, especially the TEC. To validate the speculation, La in excess of 26 mol% was added to compensate for a La 2 O 3 loss during plasma spraying, which finally resulted in a composite powder product composed of La(OH) 3 and LZ (Fig. 11a).…”

“…Hot section components working in the combustion system are designed to meet rigorous requirements to bear extreme conditions, such as elevated temperature, thermal stress, thermal shock and severe corrosion [1][2][3][4]. The use of thermal barrier coatings (TBCs) can result in a large temperature decrease between the hot gas and the metal substrate.…”
