Latest Developments in the Diamond Micropowder Industry in 2025
[Industry News] Zhengzhou, October 2025—In recent years, with the rapid development of precision manufacturing, optical electronics, semiconductors, and new energy industries, diamond micropowder, as a key subsector of superhard materials, is experiencing a new round of structural upgrades and technological innovation. By 2025, driven by multiple forces including policy regulation, technological innovation, and market demand, the global diamond micropowder industry will demonstrate a significant trend toward high-end, refined, and functional development.
Ⅰ. Tightening Export Controls, Focusing on Industry Chain Security
In early October, China’s Ministry of Commerce and the General Administration of Customs jointly issued an announcement implementing export licensing requirements for certain artificial diamond and diamond micropowder products, effective November 8, 2025. This move officially places diamond and related superhard materials on the strategic export control list, requiring exporters to apply for a license before exporting.
Industry analysts point out that diamond micropowder is widely used in high-precision manufacturing processes such as semiconductor wafer cutting, optical lens polishing, and aerospace component processing, and has potential dual-use applications. This policy adjustment not only aims to strengthen national security management of key strategic materials, but will also encourage domestic companies to accelerate technological upgrades and differentiate their product offerings, driving the industry’s transformation toward higher value-added products.
At the same time, local governments are actively responding to national policies and promoting the transformation and upgrading of industrial parks. For example, Zhecheng County, Shangqiu, Henan Province, is developing a “National Superhard Materials Industrial Base,” which has brought together over 100 diamond powder and tool manufacturers, forming a relatively complete industrial chain and providing strong support for the security of domestic diamond powder supply.
II. Market Size Steadily Expands, Demand Structure Continuously Optimizes
According to industry research data, China’s diamond powder production will reach approximately 8.14 billion carats in 2024, with a market size of RMB 2.2 billion, a year-on-year increase of approximately 6%. It is projected that by 2030, China’s diamond powder market will exceed RMB 3 billion, while the global market size is expected to grow from US$78 million in 2024 to US$120 million in 2032, with a compound annual growth rate of approximately 5.5%.
Demand growth primarily stems from high-precision polishing, optoelectronic device manufacturing, wafer dicing, ceramic processing, and thermal management materials. Among these, the semiconductor and optical applications continue to expand, placing higher demands on particle size control accuracy, particle morphology, and purity.
III. Active Technological Innovation: Surface Modification and Dispersion Control Become Hot Topics
Technological innovation will be the core driving force of the diamond micropowder industry in 2025. As downstream customers’ performance requirements continue to rise, companies are increasing their R&D investment to explore more competitive preparation and modification technologies.
1. Continuous Breakthroughs in Surface Modification and Coating Technologies
To improve the bonding between diamond micropowder and substrate materials (such as metals, resins, and ceramics), nickel plating, titanium plating, and Ni/Ti composite coatings are commonly used in the industry.
Zhejiang Jingyu New Materials recently obtained a patent for “Modified Nickel-Coated Diamond Micropowder and Its Preparation Method,” effectively improving the dispersibility and wear resistance of diamond micropowder in electroplated wire saws and thermal conductive materials.
2. Finer Particle Size Distribution and Morphology Control
New high-temperature and high-pressure synthesis equipment and grading technologies have further improved the particle size control precision of diamond micropowders. Some manufacturers can achieve particle size variation control down to 0.1μm, meeting the extremely high requirements of semiconductor wafer-level polishing.
3. Improved Agglomeration Control and Dispersion Stability
To address the problem of micropowder agglomeration and difficulty in dispersion, many companies have adopted methods such as surface coating, polymer modification, or ultrasonic dispersion to significantly improve the dispersion of micropowders in abrasive fluids and composite materials. Some companies have developed “agglomerated micropowder particles” that achieve more stable cutting and grinding performance by controlling particle morphology, demonstrating outstanding performance in the composite abrasive tool market.
IV. Enterprise Layout and Upgrading Competitive Landscape
Currently, the concentration of China’s diamond micropowder industry is increasing. Companies such as Huifeng Diamond, Changrun Diamond, Liliang Diamond, Yalong Materials, and Xinchanglai are active in technology research and development, capacity expansion, and overseas market expansion. Some companies have obtained ISO quality system certification and export their products to countries and regions such as Europe, the United States, Japan, and South Korea.
Internationally, companies such as Switzerland’s Microdiamant, Japan’s Sumitomo, and the United States’ Engis continue to lead the high-end micropowder market. Leveraging stringent quality control systems and sophisticated grading technologies, they maintain a competitive advantage in the semiconductor and optics sectors.
Notably, a new landscape is emerging in the collaboration and competition between Chinese and international companies. On the one hand, high-end clients in global wafer processing and chip manufacturing are increasing their purchases of Chinese diamond micropowder products. On the other hand, the implementation of export regulations is prompting international clients to accelerate multi-channel procurement to mitigate supply risks.
V. Future Trends: High-End, Customization, and Green Manufacturing
Based on industry trends and policy guidance, the diamond micropowder industry will develop in the following directions:
1. High-End and Precision
Companies will further upgrade from standard micropowders to ultrafine, low-defect, and high-purity products to meet the demands of high-end manufacturing in semiconductors, lasers, and precision optics.
2. Customized Services Emerge as a New Competitive Advantage
Providing customized products and technical solutions, such as particle size, morphology, and surface treatment, for different application areas will become the mainstream model in the industry.
3. Accelerating Green and Smart Manufacturing
Guided by the “dual carbon” goals, companies are promoting low-energy, high-recycling production processes while also introducing technologies such as intelligent grading and online testing to improve production line automation and yield rates.
4. Prioritizing International Expansion and Brand Building
Chinese diamond micropowder manufacturers are gradually establishing overseas warehouses and sales channels, enhancing their international brand influence and participating in global high-end supply chain competition.
Conclusion
In 2025, the diamond micropowder industry stands at a new turning point. The implementation of export regulations, technological upgrades, and diversified market demand are revitalizing this traditional superhard materials industry.
From “quantitative growth” to “qualitative improvement,” from the “abrasive era” to the “functional material era,” diamond micropowder is becoming a crucial bridge connecting advanced manufacturing and new materials technology. In the future, as Chinese companies continue to enhance their technological independence and global influence, the diamond micropowder industry is expected to enter a new stage of innovative development.
