造价堪比黄金，美日躺着赚钱的超纯铁技术，被中国“白菜价”拿下

Core Viewpoint - Ultra-pure iron, a critical material in high-tech fields, has been monopolized by the US and Japan, leading to significant challenges for China in sourcing this essential resource [1][3]. Group 1: Market Dynamics - Since the 1960s, the US and Japan have established a monopoly on ultra-pure iron through patents, equipment, and standards, pricing it at 200,000 yuan per ton, comparable to gold [3]. - In 2022, the US and Japan tightened exports under the guise of supply chain security, nearly halting China's aerospace engine and chip production lines, severely impacting companies like Huawei [5]. Group 2: Innovation and Development - In response to these challenges, China has focused on self-research and development, forming a collaborative entity in 2020 to innovate from the source rather than following the traditional methods of the US and Japan [6]. - A team led by Professor Dong Han developed the world's first fire metallurgy production line, achieving a purity level of 99.99% and overcoming the challenge of acquiring advanced equipment through independent design and manufacturing [8]. Group 3: Production and Cost Efficiency - By June 2024, China produced ultra-pure iron with a purity of 99.99992%, with only 8 kg of impurities in 100,000 tons, significantly surpassing US and Japanese products [8]. - The production cost was reduced to 40,000 yuan per ton, only one-fifth of the import price, leading to a 37% price drop in Japanese lithography materials and prompting US companies to seek collaboration [10]. Group 4: Industry Impact - The mass production of ultra-pure iron has led to substantial upgrades in downstream industries, improving the yield of 28nm chips in the semiconductor sector, extending the lifespan of turbine blades in aerospace by 30%, and increasing the range of electric vehicles by 40 km [10]. - As of January 2026, China has not only broken the US and Japan's monopoly but has also reshaped the global high-end materials market, with plans to challenge the 99.9999% purity level [12].
