The extrusion behavior of α-aluminium oxide-silicone oil pastes were investigated via capillary rheometry. Several parameters affecting the paste behavior were considered, including the viscosity of the fluid phase, the solids concentration (35 to 55 Vol. %), the extrusion rate (10~(-2) to 10~3 mm/s) and the addition of pigment. The flow curves and wall slip behavior were determined under the extrusion conditions.
