Core Viewpoint - The article discusses China's dominance in the synthetic diamond industry, highlighting its technological advancements and recent export controls that could impact global semiconductor production costs, particularly in the context of AI and high-performance computing [13][14][27]. Group 1: Synthetic Diamond Production - The majority of synthetic diamonds are produced in Henan, China, which accounts for approximately 80% of the country's total output and 95% of the global production [12]. - The development of the six-sided press machine in the 1960s marked a significant milestone, enabling China to produce synthetic diamonds independently [9][10]. - Technological advancements, such as the powder catalyst process and indirect heating techniques, have improved the efficiency and reduced energy consumption in diamond production [11][12]. Group 2: Export Controls and Strategic Implications - Recent export controls on synthetic diamond products, including micro-powder, single crystals, and grinding wheels, are seen as a strategic move to increase production costs for foreign semiconductor manufacturers [13][14]. - The export restrictions are comparable to those imposed on rare earth materials, positioning synthetic diamonds as a critical leverage point in international trade [13][14]. Group 3: Risks and Future Developments - Despite China's current advantages, there is a potential risk of foreign competitors utilizing chemical vapor deposition (CVD) methods to produce diamonds, which could lead to a shift in the market dynamics [18][19]. - The demand for diamond-based thermal management solutions in AI chips and other high-performance applications is expected to grow, creating new opportunities for the diamond industry [24][27]. - Domestic advancements in semiconductor technology, particularly in diamond substrate applications, are crucial for maintaining competitive advantages in the evolving market [27][28].
