The thermal conductivity of our samples using both hot disk and laser flash measurements gave a value of 13.3 W/m.K. This slightly lower value is expected and is indicative of residual disorder in the experimental samples, which is absent in the theoretical analysis. First-principles calculations...
Among the three dioxides, m-HfO2 is the best thermal barrier because it has the lowest thermal conductivity. 值得指出的是, 在三种氧化物中, m-HfO2由于具有最小的高温热导率而最有可能作 为热障材料应用. springer The left-side thermally-conductive heating plate (5) is connected to the nichr...
