<p>The disclosure relates to a method of binder removal from a green body before sintering or the like wherein the green body is initially heated to a temperature above the melting or flow point of the binder to liquify the binder and, at the elevated temperature, a small portion of the green body is brought into intimate contact with a non-supporting porous body of the lower capillarity potential for the liquid binder. The liquid is drawn from all parts of the green body to the region of contact between the porous body and the green body and enters the body of lower capillarity potential preferentially, removing liquid from the green body through the surface of the green body only at said region of contact. The draining is continued with or without further increase in temperature until the green body is opened or becomes permeable.</p> |
