Claim:
1. A process for constructing a silicon carbide liner for a fluidized bed reactor for production of polysilicon-coated granulate material, comprising: forming at least one coated edge surface by applying a bonding material comprising a lithium salt to at least a portion of an edge surface of a first silicon carbide segment; bringing the at least a portion of the edge surface of the first silicon carbide segment into abutment with at least a portion of an edge surface of a second silicon carbide segment with at least a portion of the bonding material positioned between the abutting edge surfaces of the first silicon carbide segment and the second silicon carbide segment; and applying heat to the bonding material, in an atmosphere devoid of hydrocarbons, to cure the bonding material and form bonded first and second silicon carbide segments, wherein the bonding material after curing comprises 0.4-0.7 wt % lithium as lithium aluminum silicate and silicon carbide.
