High grade coarse particles (30/60) cubic boron nitride passed the identification of results
On August 25, 2007, Zhengzhou Zhongnan Jiete Superhard Materials Co., Ltd. High-grade coarse particle (30/60) cubic boron nitride achievement appraisal meeting was held in Zhengzhou Jinhe Hotel, Henan Science and Technology Department, Henan Provincial Defense Department The leaders of the working committee, Zhengzhou High-tech Zone and other relevant departments attended and presided over the meeting, and hired Zhengzhou Abrasives Grinding Research Institute, China Machine Tool Industry Association Superhard Materials Branch, Zhengzhou University, Henan University of Technology and other related units. The seven experts formed the appraisal committee. Professor Wang Guangzu, a veteran of the superhard materials industry and a well-known expert, served as the chairman. Professor Li Zhihong, the secretary general of the industry association, served as the deputy director. The appraisal committee listened to the research report made by the project leader, carefully reviewed all the technical materials and related identification materials, and the microscope visually measured the product samples. It was agreed that the project solved the technical problem of high-grade coarse-grained CBN for long-term high-pressure synthesis. It can stably synthesize coarse-grained high-grade CBN single crystals in batches, which fills the domestic gap and is at the leading level in China.
