中国稀土优势相对美国究竟有多大?如何让优势进一步拉大?
转自:北京日报客户端 在今天的高科技产品中,智能手机运行流畅、屏幕色彩绚丽,电动车加速迅猛——这些卓越性能的背后,往往离不开一类特殊的材料:稀土。 镧系的 15 个元素从镧到镥,加上性质相近的钪和钇,共同构成了稀土家族。它们具有独特的磁、光、电等物理特性,能够在极小的体积内提供强大的磁力 和复杂的光电转换,成为许多尖端技术中不可替代的功能材料。 就拿新能源汽车来说,其驱动电机需要钕铁硼永磁体,单台车的稀土磁体高达 2 千克。我们来算一下,截至 2025 年 10 月,北京市新能源汽车保有量已达 120 万辆。假设这些车当中只有 2/3 处于高频使用的状态,那也相当于大概 1600 吨稀土磁体,每天在这座城市的道路上来来去去。 内置式永磁同步电机,图片来源:参考文献 [14] 更不用说隐身战机、精确制导武器等国防系统,对稀土材料的性能要求非常严苛。据估算制造一架 F35 战斗机要使用超过 400 千克稀土材料。 这意味着从日常消费电子到国家尖端武器,都离不开稳定的稀土供应。 "稀土"指 15 种镧系元素 + 钪、钇 | Z | 化学符 | 名称 | 应用范围 | | --- | --- | --- | --- ...

Core Viewpoint - The article highlights the significant transformation of China's rare earth industry, primarily driven by Xu Guangxian, who is referred to as the "Father of Rare Earth." His efforts shifted the industry from selling rare earth materials by the ton at low prices to selling high-purity products by the gram at much higher values [1][10]. Group 1: Historical Context - In the 1950s and 1960s, despite having the world's largest rare earth reserves, China lagged in technology, selling raw materials cheaply to foreign countries, which then refined and sold them back at high prices [3][5]. - Western countries tightly controlled the separation technology for rare earth elements, making it difficult for China to develop its own capabilities [3]. Group 2: Technological Development - Xu Guangxian began researching rare earth separation technology in 1972 under challenging conditions, lacking proper laboratory equipment [5]. - After ten years of experimentation, Xu established a theoretical framework for rare earth separation, significantly improving both efficiency and purity [5][8]. Group 3: Industrial Impact - By the 1980s, Xu's separation technology was applied industrially, reducing the separation time from months to days and increasing purity from over 90% to above 99.9% [8]. - Xu chose not to patent his technology, sharing it freely with national rare earth enterprises, which accelerated the industry's growth [8][10]. Group 4: Current Industry Status - Today, China controls over 80% of the global rare earth supply and has mastered core separation and purification technologies, allowing it to produce high-value rare earth products [10]. - The price of high-purity rare earth elements, such as terbium, can exceed 3 million RMB per kilogram, showcasing the dramatic increase in value compared to raw materials [10]. Group 5: Legacy and Recognition - Xu Guangxian received the National Highest Science and Technology Award in 2008 for his contributions to rare earth science, marking a significant recognition of his impact on the industry [12]. - His legacy continues to influence the development of China's rare earth industry, reflecting a broader shift from a follower to a leader in the global market [12].

Core Viewpoint - China has officially implemented export controls on rare earth materials to the United States, marking a significant shift in its strategic approach to leverage its dominance in the rare earth market [1][11]. Group 1: Historical Context - In 2010, China restricted rare earth exports to Japan amid geopolitical tensions, which led to international backlash and accusations of violating WTO rules [3][5]. - During that period, rare earth prices were extremely low, with one kilogram of rare earth oxide priced at only a few dozen yuan, while processed high-end products sold for thousands of yuan [3][5]. - Foreign countries, particularly the U.S., heavily relied on Chinese rare earth materials while simultaneously blocking China from accessing critical separation technologies [5][7]. Group 2: Technological Advancements - Chinese researchers, including notable figures like Academician Xu Guangxian and Academician Yan Chunhua, made significant breakthroughs in rare earth separation technology, achieving a purity level of 99.999% within five years [9][10]. - China now leads the world in both rare earth reserves and separation technology, capable of producing high-purity products and controlling 85% of the global market for rare earth permanent magnet materials [11]. Group 3: Strategic Implications - The timing of China's export controls is strategic, as the U.S. is attempting to rebuild its rare earth supply chain, which could take 10 to 15 years and would be significantly more costly than China's operations [13]. - The narrative emphasizes the importance of mastering core technologies and maintaining a complete industrial chain to avoid dependency on foreign resources, transforming past vulnerabilities into strategic advantages [13].
