Thermal properties of green Söderberg electrode pastes were measured up to 1073 K (800 °C) using the transient plane source method. Comparison was made to measurements on an electrode material baked beforehand to 1473 K (1200 °C). For the green pastes, thermal conductivity was found to decrease up to 673 K (400 °C) at the onset of baking. After about 873 K (600 °C), thermal conductivity of the material increases with increasing temperature. For previously baked Söderberg material, thermal conductivity continually increases with increasing temperature.

Söderberg 电极材料的热性能

使用瞬态平面源方法测量高达 1073 K (800 °C) 的绿色 Söderberg 电极糊的热性能。与预先烘烤至 1473 K (1200 °C) 的电极材料的测量结果进行比较。对于生糊，发现在烘烤开始时热导率降低至 673 K (400 °C)。在大约 873 K (600 °C) 之后，材料的热导率随着温度的升高而增加。对于先前烘烤过的 Söderberg 材料，热导率随着温度的升高而不断增加。
