Moisture Expansivity of Fired‐Clay Ceramics
Long‐term progressive moisture expansion occurs generally in fired‐clay ceramics. A new moisture expansivity property is defined in terms of the (time)1/4 power‐law model of the kinetics of long‐term moisture expansion. We show how this quantity may be determined and demonstrate its usefulness in relation with manufacture and performance. We draw particular attention to the temperature dependence of the moisture expansivity and associated practical consequences.
