AB - The current study demonstrates an efficient procedure to create ingots from Al2O3 powder using the skull melting method to use these ingots as a starting material in conventional methods for growing synthetic single-crystal sapphire.
Dimension of the cold crucible was 24 cm in inner diameter and 30 cm in inner height, 15 kg of Al2O3 powder was completely melted within 1 h at an oscillation frequency of 2.75 MHz, maintained in the molten state for 3 h, and finally air-cooled. The areal density and components of the cooled ingot by parts were analyzed through scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS). The areal density and Al2O3 content of the ingot were related to the temperature distribution inside the cold crucible during high-frequency induction heating, and the area with high temperature was high tends to be high in areal density and purity.
