Abstract
A method of thermally removing binder from porous compacts pressed from metallic or ceramic materials using atmospheric pressure and binder-free compacts produced therefrom.
Claims16
A method of removing, at about atmosphere pressure, a binder from pressed compacts containing a binder comprising heating the pressed compacts at the about atmospheric pressure and circulating or passing a sweep gas over the pressed compacts for a time sufficient to evaporate the binder from the pressed compacts and remove the evaporated binder;
- wherein the sweep gas is inert to the pressed compacts and wherein the binder is dimethyl sulfone.
Binder-free compacts prepared by removing, at about atmospheric pressure, a binder from pressed compacts containing a binder comprising heating the pressed compacts at the about atmospheric pressure and circulating or passing a sweep gas over the pressed compacts for a time sufficient to evaporate the binder from the pressed compacts and remove the evaporated binder;
- wherein the sweep gas is inert to the pressed compacts and wherein the binder is dimethyl sulfone.
