Abstract

PURPOSE:To prolong the service life of the titled crucible by fixing a carbon ring in a groove cut in the insides of divided plural carbon segments of the crucible along the circumferential direction. CONSTITUTION:A groove 1a is cut in the insides of the lower parts of divided plural carbon segments 1, 1, 1 of a carbon crucible along the circumferential direction and a carbon ring 2 is fixed in the groove 1a. At the time when SiC is formed by the reaction of Si with the carbon ring 2, the ring 2 is exchanged, so the service life of the crucible can be prolonged without exerting influence on the body of the crucible.
