MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202647126230 A) filed by Resonac Corporation on October 23, 2026, for Cubic Boron Nitride Sintered Body, Method For Producing Same, And Tool.
Inventors include Ozawa Hiromitsu; Noguchi Tsukasa; and Nakajima Takumi.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: Provided are: a cubic boron nitride sintered body having cubic boron nitride and a binder phase which is the remainder of the cubic boron nitride, in which the content of the cubic boron nitride is 50.0-90.0 vol%, the binder phase contains one or more selected from the group consisting of carbides of Ti, nitrides of Ti, carbonitrides of Ti, and borides of Ti and one or more selected from the group consisting of W2B and W2CoB2, and when the intensity of a diffraction peak attributed to the (111) plane of the cubic boron nitride is taken to be IA, the intensity of a diffraction peak attributed to the (211) plane of the W2B is taken to be IB, and the intensity of the diffraction peak of whichever of the diffraction peak attributed to the (211) plane and the diffraction peak attributed to the (310) plane of the W2CoB2 is stronger is taken to be Ic in the x-ray diffraction pattern of the cubic boron nitride with CuKa rays as the radiation source, the ratio [(IB+IC)/IA] of the total of IB and IC to IA is 0.25 or more; a method for producing the same; and a tool.
