20140261158 | FURNANCE EMPLOYING COMPONENTS FOR USE WITH GRAPHITE HOT ZONE - A furnace for growing sapphire crystal in which the furnace comprises a furnace housing; a hot zone which comprises insulation and a heater which are both accommodated within the furnace housing; a crucible located within the hot zone and the crucible has an opening. Either a crucible lid covers the opening of the crucible, and the crucible lid has a first conduit which extends therefrom or a crucible enclosure surrounds at least a side wall and a top portion of the crucible and the crucible enclosure is impermeable to at least carbon preventing carbon contamination of a melt contained within the crucible. | 09-18-2014 |
20120055396 | INTERMEDIATE MATERIALS AND METHODS FOR HIGH-TEMPERATURE APPLICATIONS - A system and method for growing crystals is described. The system includes a crucible, a shaft adapted to support the crucible, and an intermediate material between the crucible and the shaft having a coating directly applied to contact surfaces of the crucible and the shaft. The coating includes a compound, such as, a carbide, nitride, oxide, or boride. The method for growing a crystal includes providing an intermediate material between contact surfaces between a shaft and a crucible supported by the shaft prior to melting a charge material in the crucible. | 03-08-2012 |
