| abstract |
A crystalline silicon carbide fiber is provided that contains silicon carbide and boron nitride, the content of Si being 64-72 wt%, the content of C being 28-35 wt%, and the content of B being 0.1-3.0 wt%. The crystalline silicon carbide fiber is provided with, on the surface part thereof, a composition inclination layer in which the content of the silicon carbide increases and the content of the boron nitride is reduced moving in the depth direction. |
