METHOD FOR MANUFACTURING POROUS CERAMIC ARTICLES WITH REDUCED SHRINKAGE
PROBLEM TO BE SOLVED: To provide a method for manufacturing porous ceramic articles, in which the method includes a step of forming a plurality of extruded green bodies from a ceramic precursor batch composition.SOLUTION: A method includes a step of forming a plurality of extruded green bodies from a ceramic precursor batch composition. The method also includes the steps of: calcining the extruded green bodies in a tunnel kiln (10) to produce porous ceramic articles; periodically determining a shrinkage characteristic of at least one sample passing through the tunnel kiln; and adjusting a top soak temperature in the kiln if the shrinkage characteristic is outside of a predetermined range.SELECTED DRAWING: Figure 1
