CONVECTIVE STRUCTURE WITH A SAPPHIRE SINGLE CRYSTAL MANUFACTURING EQUIPMENT

摘要

In the present invention, disclosed is a sapphire single crystal manufacturing device with a convective structure. The disclosed sapphire single crystal manufacturing device with a convective structure comprises a crucible for melting aluminum oxide; a crucible supporting frame for supporting the lower part of the crucible; a rotation axis for rotating the crucible supporting frame; and a side heater installed on the side part of the crucible for heating the crucible. In the device, a plurality of convective holes are formed on the crucible supporting frame and heat released from the side heater heats the lower part of the crucible through the plurality of convective holes.
