Spalling characteristics of aluminosilicate refractories in relation to their chemical and mineralogical composition
TL;DR: In this paper, the effects of shape, size and relative proportions of the crystalline phases usually present in the aluminosilicate refractories on their thermal-shock resistance are compared.
Abstract: Thermal-shock resistance of aluminosilicate refractories is influenced by their chemical composition and mineralogical constitution. Attempts have been made in this paper to compare the effects of shape, size and relative proportions of the crystalline phases usually present in the aluminosilicate refractories on their thermal-shock resistance.

TL;DR: The thermal expansion of hard porcelain samples is a function of the asymmetry of size distribution of mullite crystals and internal stresses originating in the samples from the thermal expansion mismatch between the phases also influence the thermal-shock resistance as mentioned in this paper.
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 size-distribution of mullite crystals.

TL;DR: In this article, the effects of mechanical strength, linear thermal expansion and modulus of elasticity on thermal-shock resistance of alumino-silicate refractories have been studied and the results have been statistically analyzed.
Abstract: The effects of mechanical strength, linear thermal expansion and modulus of elasticity on thermal-shock resistance of alumino-silicate refractories have been studied and the results have been statistically analysed. An equation correlating thermal-shock resistance of these refractories to their strength, thermal expansion and modulus of elasticity has been suggested on the basis of the observations made.
