摘　　要：研究了研磨时间、分散剂掺量、固含量对A l2O3-TiO2料浆流变性能的影响。研究结果表明,当研磨时间为4 h,分散剂掺量为3%(mass fraction of solid)、固含量为45%(volumefraction)的条件下所制备的A l2O3-TiO2粘度仅为76 mPa.s,引入固化剂后固化时间为360s。该料浆流动性能最佳,固化时间充裕,有利于注凝成型。The effect of mill time, dispersant content and solid volume fraction on rheological behaviors of Al2O3 - TiO2 slurry were investigated. The results showed that the viscosity of Al2O3 - TiO2 slurry was only 76 mPa·s and the solidification time was 360s after adding solidified agent when the mill time was 4h,the additive of dispersant was 3% （ mass fraction of solid） ,and the solid volume content was 45%. And this slurry obtained the best fluid performance and abundant solidification time, was propitious to geleasting.
