[Object] To provide a sialon sintered compact having a high hardness and a wear-resistant component made of the sintered compact. n [Solution] A sialon sintered compact includes a main phase made of α-sialon, and a sub phase made of β-sialon. The molar concentration of aluminum in the β-sialon is higher than the molar concentration of aluminum in the α-sialon. Such a sialon sintered compact can exhibit high strength. A wear-resistant component made of the sialon sintered compact exhibits a high hardness, and accordingly has high reliability. |
