JOINT DESIGN FOR SEGMENTED SILICON CARBIDE LINER IN A FLUIDIZED BED REACTOR

摘要

Segmented silicon carbide liners for use in a fluidized bed reactor for production of polysilicon-coated granulate material are disclosed, as well as methods of making and using the segmented silicon carbide liners. Non-contaminating bonding materials for joining silicon carbide segments also are disclosed. One or more of the silicon carbide segments may be constructed of reaction-bonded silicon carbide.

主权项

1. A segmented silicon carbide liner for a fluidized bed reactor for production of polysilicon-coated granulate material, comprising:
a first silicon carbide segment having a first segment upper edge surface defining one of an upwardly opening first segment depression or an upwardly extending first segment protrusion; a second silicon carbide segment located above and abutted to the first silicon carbide segment, the second silicon carbide segment having a second segment lower edge surface defining a downwardly opening second segment depression if the first segment upper edge surface defines an upwardly extending first segment protrusion or a downwardly extending second segment protrusion if the first segment upper edge surface defines an upwardly opening first segment depression, the protrusion being received within the depression and having smaller dimensions than the depression such that the surface of the depression is spaced apart from the surface of the protrusion and a space is located between the protrusion and the depression; and a volume of bonding material comprising a lithium salt, the bonding material disposed within the space between the protrusion and the depression.
