中国地位不保?美国稀土技术革命性突破,或重塑全球稀土产业格局

稀土元素,被誉为现代科技的"隐形基石",广泛应用于手机、芯片、新能源汽车、核磁共振仪等高科技设备中。 然而,原本全球稀土供应长期高度集中于中国,但近日,美国科学家在海洋中发现了一条全新路径:利用海藻提取稀土。 这种看似普通的海洋植物,竟能高效吸收和富集稀土元素,为全球高科技产业提供了新的原材料来源。 中国地位不保?美国稀土技术革命性突破,海藻"淘金术"的出现,或重塑全球稀土产业格局! 长期以来,海洋被认为是地球上潜藏稀土的重要储藏地,但问题在于海水中稀土元素含量极低,几乎像在一大桶水里寻找几粒盐。 传统直接从海水提取稀土,不仅成本高昂,而且难以满足工业化需求。 美国太平洋西北国家实验室的科学家们,在长期研究海洋生态系统后,发现了一种意想不到的天然"矿工":海藻。 这些海洋植物天生具有浓缩稀土的能力,其吸收机制不仅稳定环保,而且极具可持续性。 科学家们在华盛顿州塞奎姆湾对多种海藻进行了系统实验,结果显示,海藻可以将周围水体中的稀土元素浓缩至百万倍以上。 这种稀土并非简单附着在海藻表面,而是通过代谢机制被主动吸收并固定在细胞内部,形成生物矿化储存。这意味着海藻天然成为了一座微型稀土储藏库, 可在沿海国家的海域中实 ...
