Abstract
It is difficult for a Cr—Si-based sintered body composed of chromium silicide (CrSi) and silicon (Si) to have high strength. Provided is a Cr—Si-based sintered body including Cr (chromium) and silicon (Si), in which the crystal structure attributed by X-ray diffraction is composed of chromium silicide (CrSi) and silicon (Si), a CrSiphase is present at 60 wt % or more in a bulk, a density of the sintered body is 95% or more, and an average grain size of the CrSiphase is 60 μm or less.
