The rheological properties (flow curves and viscoelastic behavior) of injection moulding suspension prepared from nanosized plasma processed AlN powder and paraffin wax were investigated in the broad region of shear rates (0.07-1350 s-1). Two viscosity platoaux are observed on the flow curves and the values of two yield stresses are obtained. The linear viscoelastic region is not reached at the lowest deformation amplitude (0.66 %). Higher values of dynamic viscosity than those of effective viscosity at 'gamma'='omega' are observed in all the range of the used frequency and shear rate (0.1-80 s-1). The rebuilding of destroyed particle packing structure during ultrasound or shear treatment is observed. It results in the dependence of rheologic properties on the pretreatment history of suspensions.
