Abstract: Methods for making ceramic articles, and methods for reducing extrusion pressure during processes of making ceramic articles, are disclosed. The methods include mixing a ceramic batch composition comprising amylose and amylopectin in an amylose:amylopectin ratio ranging from about 30:70 to about 95:5, and extruding the ceramic batch composition through an extrusion die to form an extruded green ceramic article.

Abstract: Disclosed herein are methods for controlling and/or predicting the shrinkage and/or growth of a ceramic honeycomb structure between a green body state and a fired state by adjusting the hydrated alumina content of the batch composition. Also disclosed herein is substantially clay-free cordierite honeycombs produced in accordance with such methods.

Abstract: An extrusion apparatus including a die and a mask are provided such that no slots feed directly into the longitudinal skin forming gap between the mask and the die. In a method of forming a die adapted to improve skin uniformity of extruded cellular ceramic substrates a slotted block of die material is provided including central slots adapted to form a cellular matrix of the substrate and peripheral slots located outwardly of the central slots designed to be covered by a skin former mask and adapted to extrude peripheral batch material. An arcuate skin former is cut corresponding to a target shrinkage so as to intersect the slotted block such that skin flow from tangent slots at 90 degree positions of the die is limited to the peripheral batch material.
