固体爆轰产物（烟灰）中碳的物理结构和化学键合在很大程度上是未知的。众所周知，金刚石可以通过对装在炸药中的石墨或装在炸药外部的夹具中的石墨施加爆炸冲击来制造。在这里，我们报告的钻石的形成作为爆炸过程本身的化学产品。我们观察到的钻石直径为4-7 nm，占烟尘的25wt%;在尺寸和红外光谱方面，它们类似于从陨石中分离出来的钻石。
The physical structure and chemical bonding of the carbon in solid detonation products (soot) are largely unknown. It is well estab-lished that diamond can be manufactured by the application of explosive shocks to graphite loaded into the explosive, or in a fixture external to the explosive1. Here we report the formation of diamonds as a chemical product of the detonation process itself. The diamonds we observe are 4–7 nm in diameter and make up 25wt% of the soot; in size and infrared spectrum they resemble diamonds similarly isolated from meteorites2.
