Enhancing the thermal insulating properties of lanthanum zirconate porous ceramics via pore structure tailoring
TL;DR: In this paper, the pore structures were tailored by varying the initial solid loading of the slurry, and the as-prepared ceramics exhibited an interconnected pore structure with high porosity (67.9 % −84.2 %), low thermal conductivity (0.083 −0.207 W/(m·K)), and relatively high compressive strength (1.56 −7.89 MPa).

Thermal shock behavior of 8YSZ and double-ceramic-layer La2Zr2O7/8YSZ thermal barrier coatings fabricated by atmospheric plasma spraying
TL;DR: In this paper, the authors investigated the thermal shock behavior of three as-sprayed TBCs at 1000°C and 1200°C with NiCrAlY as the bond coat, and the results indicated that the thermal cycling lifetime of the double-ceramic-layer (DCL) TBC is longer than that of SCL 8YSZ TBC due to the fact that the DCL LZ/8YSZ further enhance the thermal insulation effect, improve the sintering resistance ability and relieve the thermal mismatch between the ceramic layer and the metallic layer at
