Zusammenfassung: | A method for green-to-fired shrinkage control in honeycomb ceramic article manufacture, including: measuring, prior to mixing, the particle size distribution properties of at least one fine particle size graphite pore former ingredient of a provided ceramic source batch mixture; calculating the expected shrinkage of the green body to the fired ceramic article based on the measured particle size distribution properties of the at least one fine particle graphite pore former; making the honeycomb ceramic article; measuring the shrinkage of the resulting fired honeycomb ceramic article; and adjusting the ceramic source batch mixture in a subsequent batch material schedule, as defined herein, wherein the adjusted ceramic source batch mixture provides finished honeycomb ceramic articles having controlled green-to-fired shrinkage. |
