Abstract:
In the present invention, in producing a SiC single crystal in accordance with a solution method, a crucible containing SiC as a main component and having an oxygen content of 100 ppm or less is used as the crucible to be used as a container for a Si—C solution. In another embodiment, a sintered body containing SiC as a main component and having an oxygen content of 100 ppm or less is placed in the crucible to be used as a container for a Si—C solution. SiC, which is the main component of these, serves as a source for Si and C and allows Si and C to elute into the Si—C solution by heating. Since the oxygen content of SiC is 100 ppm or less, generation of gas in the Si—C solution is suppressed.

Claim (Index 16):
The method of producing a SiC single crystal according to  claim 2 , wherein the heating is carried out in a state where the crucible is housed in a second crucible made of a heat-resistant carbon material.
