摘　　要：The effects of several commercial dispersants,including AN 2000,ammonium polyacrylate,sodium tripolyphosphate,sodium hexametaphosphate, and of solids loading and of electro fused magnesia on rheological properties of aqueous alumina spinel slurries were studied. The results reveal that AN 2000 is the most effective one among the selected dispersants for alumina spinel slurries. With 0.5% weight of AN 2000, the 57vol% solids loading alumina spinel slurry with viscosity of 0.37 Pa·s was obtained at shear rate of 50s 1 .The effects of several commercial dispersants,including AN 2000,ammonium polyacrylate,sodium tripolyphosphate,sodium hexametaphosphate, and of solids loading and of electro fused magnesia on rheological properties of aqueous alumina spinel slurries were studied.
