摘要

The Sr0.95Sm0.0125Dy0.0125 square 0.025Ti0.90Nb0.10O3 +/-delta/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.
