（文章来源：证券日报） 证券日报网讯 2月12日，中国铝业在互动平台回答投资者提问时表示，氧化镓作为第四代超宽禁带半导 体代表材料，公司正在开展相关研究工作。 ...

如果有一种新材料，能让你的新能源车，15分钟充满电，并增加续航。你会认为，它值多少钱？ 这种材料就是氧化镓。 最近，这个赛道跑出一只未来独角兽：铭镓半导体。 它刚刚完成第5轮超亿元融资，由彭程创投、成都科创投集团、天鹰资本、河南国煜基金、洪泰基金联合投资。截至目前，累计融资近4亿元。 目前，铭镓半导体的产品已量产：氧化镓4英寸晶圆已出货，6英寸晶圆已稳定，并与华为、比亚迪、中科电科等企业达成合作，月收入已达千 万级。 铭镓半导体创始人陈政委是一名"85后"，生长在河南安阳，本科毕业于天津工业大学，并在日本国立佐贺大学获得博士学位。 最近，铅笔道与陈政委交流氧化镓的商业化机会，精华如下： 1、氧化镓的长期痛点是啥？ 材料很贵，且不容易买到。 2、它的攻克难点是什么？ 材料投入大、周期长、回报慢，失败风险很高。 3、它可以用来干啥？ 降低家电电费，加快新能源车充电，提高工业能源利用率等。 4、投资人的长期误区是什么？ 认为氧化镓既没有市场规模，也没有商业化想象空间。 日本起步早，财团主导投资；国内优势是市场大、反应快、工程师红利。 6、未来趋势？ 预计2030年，中国与全球平分秋色。 01 "王炸"材料 第一次见 ...

为啥这玩意儿这么抢手？不光是稀缺，更因为它的性能堪称"半导体天花板"，能轻松碾压前几代材料。咱们用大白话来说，前几代半导体在极端环境下早 就"扛不住"：硅基芯片一遇高压就容易击穿，第三代碳化硅在超高温下性能会大幅衰减，而第四代半导体能轻松应对万伏高压、千度高温和强辐射的极限场 景。比如氧化镓的电压承受能力是硅材料的10倍，电能损耗仅为硅元件的四十九分之一；金刚石的散热能力是铜的4倍，能解决量子芯片、AI芯片的散热难 题；氮化铝能扛住2200℃高温，是核反应堆、深空探测设备的唯一选择。 先说说这第四代半导体材料，到底有多金贵、多稀缺。它的核心是氧化镓、金刚石、氮化铝这三类特种材料，其中最关键的原料锑，在地壳中的含量只有十 万分之六点五，仅为稀土的百分之一，稀缺度直接翻倍。更难得的是，自然界中虽然有上百种含锑矿物，但真正能实现工业化开采、满足半导体生产标准 的，满打满算也就10种，堪比"矿产界的大熊猫"。中美欧早就把它列入关键矿产名录，和石油、稀土并列，足见其战略价值有多重要。 放在几年前，这一领域还被西方牢牢攥在手里，美国垄断了高端金刚石衬底市场，日本掌握着氧化镓晶体的核心制备技术，甚至禁止向中国出口2英寸以上 ...

Core Viewpoint - The article discusses the strategic implications of China's export controls on gallium, highlighting its critical role in the semiconductor and defense industries, and the potential economic impact on the U.S. and its allies due to reliance on Chinese supply [4][8][39].
