Molten Magnesium

The types and structures of oxide phases produced during the incongruent reduction of sapphire (single-crystal Al2O3) by molten magnesium were examined. Polished faces of sapphire were exposed to molten magnesium at 1000 °C for 100 h. Such exposure resulted in the formation of a continuous, epitaxial layer of spinel (MgAl2O4) on sapphire and a continuous, epitaxial layer of magnesia (MgO) on the spinel. X-ray pole figure analyses indicated that two variants of spinel and magnesia had formed in a manner consistent with the following orientation relationships:
