Title:
INTERMEDIATE MATERIALS AND METHODS FOR HIGH-TEMPERATURE APPLICATIONS
Document Type and Number:
WIPO Patent Application WO/2012/054845
Kind Code:
A3
Abstract:
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.
