Abstract
This investigation deals with the solid extrusion of
plasticised alumina as a preliminary step towards preparation
of refractory tubes. The effectiveness of certain
organic binders, and the amounts necessary have been
examined. Sample bars have been prepared from a mix
by ram extrusion and some of their physical properties
determined. It appears as a result of this study that gum
tragacanth is a suitable binder and two per cent would be
sufficient for the extrusion of a plasticised mix of alumina
fines such as the ones encountered in this investigation.
