<P>PROBLEM TO BE SOLVED: To provide a sintered compact whose reactivity with a workpiece is reduced while maintaining its high strength and hardness, and a cutting tool excellent in wear resistance. <P>SOLUTION: The sintered compact comprises: cubic crystal boron nitride; a first compound; and a second compound, wherein the content of the cubic crystal boron nitride is 35 to 93 vol.%. The first compound is at least either selected from cubic crystal sialon or cubic crystal silicon nitride. The second compound is at least one compound selected from the group consisting of α-sialon, β-sialon, α-silicon nitride and β-silicon nitride. <P>COPYRIGHT: (C)2011,JPO&INPIT |
