  • Method for forming parts from inorganic particulate material
    Patent number: 5723083
    Abstract: A method for forming parts from inorganic particulate materials is diclosed. The method utilizes a two-component binder composition which is removable at a faster rate than conventional binder compositions, thereby reducing the formation of voids and cracks that occur during binder removal. No toxic materials are required and the method does not rely on solvents. The method may be used with ceramics, metals, and cermets.
