The main purpose of this project has been established. The equipment has been successfully developed and it is working well. From the results of analysis using obtained data, the factors affecting the thermal conductivity measured by present system have been clarified, which were convection, radiation and electron conductivity for ionic slag melt. In high temperature region more than 800℃, a contribution of radiation on the apparent thermal conductivity was significant. Moreover, it was found that the radiation energy from the thermocouple (Pt) affected the measurement of thermal diffusivity, especially for the transparent stag. The effect of radiation was eliminated by theoretical calculation and reasonable values have been obtained.

该项目的主要目的已经确定。该设备已研制成功，运行良好。通过对实验数据的分析，阐明了影响离子渣熔体导热系数的因素是对流、辐射和电子传导。在800℃以上的高温区，辐射对表观导热系数的贡献较大。此外，还发现热电偶（Pt）的辐射能量对热扩散率的测量有影响，尤其是对于透明的金属板。通过理论计算消除了辐射的影响，得到了合理的数值。
