Abstract: A method of making a near-net superhard material body includes preparing granules from a mixture of superhard powder, binders, and fluids, compacting the granules to form a soft green complex-shaped body, heating the soft green body in a furnace to form a hard green body free from residual binders, embedding one or more of the hard green bodies in a containment powder or a containment means and forming a pressure cell, sintering the cell at high pressure and high temperature, and removing the containment powder from the cell or removing the inserts from the containment means to reveal one or more near-net bodies.

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. The SiC crucible and SiC sintered body are obtained by molding and baking a SiC raw-material powder having an oxygen content of 2000 ppm or less. 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.
