在800 ~ 1000℃的宽温度范围内，研究了ni -钪稳定氧化锆（Ni-ScSZ）陶瓷的制备条件对其耐积碳性能的影响。NiO-ScSZ混合物在用作金属陶瓷电极之前经过预热处理。虽然ScSZ在ni基陶瓷中对积碳的抑制作用是众所周知的，但本研究揭示了制备方法和烧制条件对积碳行为的影响。在1400℃下加热得到的Ni-ScSZ陶瓷表现出特殊的积碳行为。该样品在800 ~ 900℃时的初始沉积速率大于1000℃时的初始沉积速率，而其他样品的沉积速率随温度的降低而降低。经1400℃热处理后的ScSZ为立方相稳定，而NiO热处理前的ScSZ为菱形相。这些结果表明，高温热处理诱导了NiO与ScSZ之间的强相互作用。
The influence of the preparation condition of Ni-scandia-stabilized zirconia (Ni-ScSZ) cermet on the tolerance to carbon deposition was investigated in the wide temperature range of 800-1000°C. The mixture of NiO-ScSZ was subjected to preheat-treatments prior to use as a cermet electrode. Although the inhibitory effect of ScSZ in Ni-based cermet for carbon deposition is well known, the present study revealed that the preparation method and firing condition influenced the carbon deposition behavior. The Ni-ScSZ cermet obtained from the oxide mixture heated at 1400°C showed peculiar behavior to carbon deposition. The initial carbon deposition rate at 800-900°C for this sample was larger than that at 1000°C, whereas other samples exhibited a reduction in deposition rate with decreasing temperature. The cubic phase stabilization in ScSZ was confirmed for the sample treated at 1400°C, though ScSZ was in the rhombohedral phase before the heat-treatment with NiO. These results suggested that a strong interaction between NiO and ScSZ was induced by the high-temperature heat-treatment.
