Abstract

The Sr0.95Sm0.0125Dy0.01250.025Ti0.90Nb0.10Oδ/ZrO2 composite was directly prepared through spark plasma sintering. This approach limited the grain growth and facilitated the achievement of a narrow grain size distribution due to fast sintering and ZrO2 effects. Thermal conductivity declined to 1.68 W m−1 K−1, which is the lowest among the reported values for micro-polycrystalline SrTiO3-based structures.
