Summary

A water-based binder system for low pressure piston-type extrusion of alumina was developed. The binder system consists of colloidal AlO(OH) and ≈O.3 wt.% polyvinyl alcohol (PVA). Two different types of alumina powder (Alcoa SG-Al6 and Sumitomo AKP-30) were evaluated with regard to their extrusion pressure, binder burnout, physical properties at green and fired states, and densification behavior.
