ABSTRACT:
A silicon-carbide sintered article prepared by permeating molten silicon into a carbon compact of elemental carbon, wherein Lc(002), which indicates a length of a domain in the direction perpendicular to the C(002) surface of elemental carbon in the carbon compact, is up to 1000 angstrom. The resulting article includes silicon carbide, silicon, and up to about 1 percent by weight of residual elemental carbon based on the sum of the silicon carbide and the silicon.
