钻石恒久远，一颗永流传——但当它被用在导弹制导系统上时，游戏规则就彻底改变了。10月9日，中国商务部与海关总署联合发布公告，对超硬材料及其 相关技术实施出口管制，直指美国军工与半导体产业的"咽喉"。 这一刻，被誉为"工业牙齿"的超硬材料，已从车间走向战场。中国在全球超硬材料市场已形成绝对性统治。数据表明，咱们中国超硬材料工业的总产值大概 有1000亿元。在金刚石和立方氮化硼单晶的产量上，咱们国家可是排在世界第一的。特别是工业金刚石，产量超过了全球总产量的95%。 郑州在产业集聚区发展指数的综合评价里，可是排第一的。它的产业链覆盖度超过了70%，已经形成了一个以高新区为核心的产业集群。这次出口管制，主 要管的不是普通的培育钻石，而是有战略意义的"功能性金刚石"。这种特殊的金刚石跟普通钻石可不一样，它有很高的红外透过率和很低的光学自发射率， 从深紫外到微波毫米波段，都能很好地透过。 就因为这一特性，它成了发展机载、弹载、舰载等红外搜索与跟踪系统里，光学窗口和整流罩的关键材料。在高功率微波武器、高能激光武器等新型武器系 统、核反应堆ECRH用介质窗、太赫兹波段用行波管等领域，功能性金刚石同样不可或缺。 美国和日本很 ...
