Abstract
Thermal-shock resistance of hard porcelain samples are dependent on the concentrations
of the crystalline phases (mullite and quartz) and the glassy phase and also
on the size of mullite crystals. Internal stresses originating in the samples from the
thermal expansion mismatch between the phases also influence the thermal-shock
resistance. The thermal expansion of the samples is a function of the asymmetry of sizedistribution
of mullite crystals.
