ABSTRACT:
There is provided a method of removing binding material from a shaped preform (green body) in the preparation procedure for the manufacture of ceramics from particulate materials by a new method comprising exposing the green body to a liquidified fluid to dissolve the binder materials in a liquidified fluid without deformation of the shape of the article. In the method, the binder materials can be removed without swelling of the article because the green body is not exposed to a rapid temperature increase and the binder does not volatilize in the body. Further the binder material can be removed in a shorter period of time from the entire body.
