The perovskite BaBiO$_3$ crystallizes in a cubic structure and undergoes structural transitions toward lower symmetry phases upon cooling. The two low-temperature monoclinic phases are insulating, and the origin of this unexpected non-metallic character has been under debate. Both monoclinic phases exhibit tilting and breathing distortions, which are connected with the insulating nature of this compound and may have important effects on phononic heat conductivity. Here, we report the first thermal conductivity measurement, $kappa$(T), in pristine polycrystalline BaBiO$_3$ from 1.5 K to 310 K. At low and intermediate temperatures, we observe features reminiscent of a glass-like behavior, whereas at high-temperatures we find a downturn - typical of a crystalline solid. We compare our findings with available data of other recently investigated perovskite oxides displaying similar temperature dependence.
透辉石 BaBiO$_3$ 以立方结构结晶，并在冷却时发生向低对称相的结构转变。两种低温单斜相具有绝缘性，这种意想不到的非金属特性的起源一直备受争议。两种单斜相都表现出倾斜和呼吸畸变，这与该化合物的绝缘性有关，并可能对声波导热性产生重要影响。在这里，我们首次报告了从 1.5 K 到 310 K 原始多晶 BaBiO$_3$ 的热导率测量结果 $kappa$(T)。我们将我们的发现与最近研究的其他具有类似温度依赖性的包晶氧化物的现有数据进行了比较。
