Abstract
Disclosed are a silicon carbide sintered body and a sliding component using the same, and a protective body which, even when fine cracks are generated due to thermal shock or mechanical impact over prolonged use, are capable of inhibiting development of the cracks. The silicon carbide sintered body contains silicon carbide grains as a major component and has a relative density of 95% or more. On an observation surface of the silicon carbide sintered body, coarse silicon carbide grainshaving a surface area of 170 μmor more occupy 6 area % or more and 15 area % or less. The silicon carbide sintered body has excellent mechanical properties such as strength and rigidity. Even when fine cracks are generated due to thermal shock or mechanical impact, coarse silicon carbide grainsare capable of inhibiting development of the cracks.
