在微纳世界刻下中国尺度—— 一颗纳米金刚石的国际标准之路

Core Viewpoint - The release of the ISO 6031:2025 standard, led by Henan United Precision Materials Co., Ltd., marks a significant milestone for China's ultra-hard materials industry, transitioning from a follower to a leader in international standards for nano-diamond materials [1][2]. Group 1: Industry Significance - Ultra-hard materials, particularly diamonds, are essential in high-end manufacturing due to their superior physical and chemical properties, finding applications in aerospace, defense, and advanced technology sectors [1]. - The Chinese diamond production accounts for over 95% of the global output, yet high-end products still rely on imports, indicating a need for quality upgrades and standardization [4]. Group 2: Standardization Efforts - The ISO 6031:2025 standard provides a unified technical language and quality benchmarks for global nano-diamond producers and polymer composite manufacturers, enhancing industry coherence [2]. - Henan United Precision Materials has a strong technical foundation in nano-diamond preparation and application, successfully applying its materials in various fields such as high-performance composites and biomedical applications [2]. Group 3: Research and Development - The Zhengzhou Abrasives Research Institute has been pivotal in promoting Chinese standards internationally, having developed significant innovations in the ultra-hard materials sector since its establishment in 1958 [2][3]. - The institute has addressed common industry challenges by developing precise testing methods for diamond impurities and improving the formulation analysis of abrasive tools, significantly reducing product development cycles [3]. Group 4: Future Development Plans - Henan Province has outlined a clear development path for the ultra-hard materials industry, focusing on upstream customization, midstream calibration technology, and downstream quality evaluation systems [4]. - The implementation of the "Action Plan for Cultivating and Expanding the Ultra-Hard Materials Industry Chain (2023-2025)" aims to transition the industry from a "tool era" to a "functional era," fostering a globally competitive ultra-hard materials industry cluster [4].
