The resultant morphologies of the sapphire-anorthite-liquid interfaces were corrugated and quite different depending on the crystallographic orientation of the sapphire; all the planes perpendicular to the C-plane showed fingerlike morphologies, while long parallel segments were detached from the basal C-plane. The results were interpreted in terms of coherency-strain-induced instability of the solid-liquid interface (ISLI) caused by the alloying of Cr2O3 into sapphire. The difference in microstructural evolution depending on crystallographic orientation was explained in terms of strong anisotropy of the solid-liquid interface characteristics.
