摘　　要：本工作详细研究了碳黑粉、固含量、球磨时间、分散剂用量和pH值对NiO/YSZ陶瓷料浆流变性质的影响。结果表明:料浆均表现出剪切变稀行为,且为假塑性流体;确定了最佳实验参数,当pH=9,分散剂用量为2%(体积分数),球磨4h的NiO/YSZ水基料浆稳定性好,适合于成型SOFC的Ni/YSZ阳极材料,并最终制备出体积分数为50%,适合浇注的NiO/YSZ陶瓷料浆。Effects of carbon black powders, solid loading, milling time, contents of dispersant and pH value on rheological properties of NiO/YSZ ceramic slurry were investigated by rheograms in detail. Results show that shear thinning behaviour and pseudoplasticity of aqueous slurries can be found. The pH value is optimized to 9. Contents of dispersant are equal to 2%（volume fraction）. It is suitable to fabrication of Ni/YSZ anode material after NiO/YSZ aqueous slurries were milled 4h. Ultimately volume fractions of NiO/YSZ aqueous slurries reach 50%.
