Abstract:
A method of making ceramic articles includes compounding ceramic precursor batch components that include hydrous clay. The hydrous clay includes particle components having a platy geometry. The crystallite size of the platy hydrous clay particle components is greater than a predetermined amount. Controlling such crystallite size can result in reduced shrinkage of green ware during the clay dehydroxylation stage of firing.
