Abstract
Plasticized inorganic powder batches comprising a cellulosic binder, water, and at least one inorganic powder exhibiting relatively high water affinity are compounded by combining the inorganic powder, prior to any contact with the water or cellulosic binder, with an organic surface treatment agent to decrease the water affinity thereof; subsequent mixing of the treated powder with the water and the cellulosic binder forms a plasticized inorganic powder batch with improved extrusion, molding, or other shaping characteristics.
