| Abstract: | The effects of dispersant amount and solids loading on rheological behaviors of aqueous BeO suspensions were investigated. The relationship of viscosity and solids loading determined experimentally was compared with five various existing models. BeO aqueous suspensions exhibited a shear dependent behavior from shear thinning to shear thickening with the increasing of shear rate. The rheological behaviors of the suspensions are in reasonable accord with the model proposed by Liu, and are basically consistent with the Dabak model and Chong model, but are discrepant to other two models proposed by Krieger–Dougherty and Kitano. The maximum solids loading is estimated to be 0.577. |
