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 less than a predetermined amount. Controlling such crystallite size can result in fired ceramic articles with a lower coefficient of thermal expansion and improved thermal shock resistance.
