SILICON CARBIDE-TANTALUM CARBIDE COMPOSITE AND SUSCEPTOR

摘要

Provided is a silicon carbide-tantalum carbide composite having excellent durability. A silicon carbide-tantalum carbide composite (1) includes: a body (10) whose surface layer is at least partly formed of a first silicon carbide layer (12); a tantalum carbide layer (20) ; and a second silicon carbide layer (13). The tantalum carbide layer (20) is disposed over the first silicon carbide layer (12). The second silicon carbide layer (13) is interposed between the tantalum carbide layer (20) and the first silicon carbide layer (12). The second silicon carbide layer (13) has a C/Si composition ratio of not less than 1.2 as measured by X-ray photoelectron spectroscopy. The second silicon carbide layer (13) has a peak intensity ratio G/D of not less than 1.0 between the G-band and D-band of carbon as measured by Raman spectroscopy.
