中国打破美日垄断!人造太阳核心材料国产化 核聚变技术迎来新突破
Sou Hu Cai Jing· 2025-10-30 12:40
中国在核聚变材料领域完成了一个影响深远的大动作,这事不仅解决了关键技术难题,也彻底扭转了以 往受制于国外供应链的格局。 很长一段时间,我们在高温超导带材这块有着全球领先的制造实力,但真正决定性能和安全的哈氏合金 基带,却被美日牢牢把持。高昂的采购成本和一年等货的周期让产业发展步步受限,更别提对手一点头 就能断供,谁也不愿把前途全押在别人身上。 文案|编辑:凤梨 中科院金属所的科研团队硬是把这个难题从根上攻克了。他们做出的哈氏合金基带不光纯度高、细度 高,机械性能也达到了国际顶尖水平。别看这小小一根基带,比头发还要细得多,整卷拉上千米长,性 能一点不打折扣。 要把它做到每一毫米杂质极少、表面要像镜子一样平整,还要能在极冷或者极烫的环境下保持强度,这 事儿可不是在哪家实验室拍脑门就完成的。 核聚变用的是海水里提取的燃料,要是真能做成,能源比现在便宜又干净。有人说这是通往新世纪的入 口,不掌握材料技术就只能被动观望,现在中国已经走到了前排。 背后是无数次的磨炼和大胆创新,中国团队把国际标准都甩在后边,真正实现工业化量产。而且用国产 的价格一下降了三四成,供货速度也比以往快三四倍,不只是能做得出来,更能做得好做得快。 ...
