Summary

Capillary extrudate analysis was performed on two aqueous alumina pastes having average particle sizes of 1 and 5 μm, respectively. The batches were composed of hydroxypropyl methylcellulose binder and a stearate lubricant Extrusion as a function of solids loading, batch mixedness, and extrusion velocity was measured. Results show that the initial particle size and solids loading influenced the uniformity and appearance of the cylindrical extrudates. Further variation of particle size distribution showed a strong pressure versus length/diameter relationship.
