摘要
pThis is to provide a cubic boron nitride sintered body excellent in wear resistance. The cubic boron nitride sintered body comprises about 30 to about 70% by volume of cubic boron nitride; and as the reminder, a binder phase comprising at least one selected from an oxide, carbide, nitride and boride of Ti, Al, Zr, Y, Ce, Mg or Ca and mutual solid solutions thereof; and inevitable impurities, wherein the cubic boron nitride sintered body contains ±-type Al 2 O 3 , ZrB 2 , ZrO 2 and ZrO, and when an X-ray diffraction intensity of a (110) plane of ±-type Al 2 O 3 is represented by Ia, an X-ray diffraction intensity of a (101) plane of ZrB 2 is represented by Izb, and an X-ray diffraction intensity of a (111) plane of ZrO is represented by Izo, (Izb/Ia) which shows a ratio of Izb based on Ia satisfies 0.13‰¦(Izb/Ia)‰¦0.30, and (Izo/Ia) which shows a ratio of Izo based on Ia satisfies 0.05(Izo/Ia)0.20./p[EP2500332A1]
