设在美国纽约州斯克内克塔迪市的通用电气研究与发展中心(GE)的化学家用含有过量的中子的碳制成了人造金刚石。GE的化学工程师W·F·班霍尔泽说:“天然金刚石一般含碳13同位素不足1％,而这种新金刚石却含有碳13同位素达99％。完成这项分析的同行,福特汽车公司H·霍格韦说:“用高分辨率的X射线衍射仪测量了天然金刚石和五个GE的人造金刚石,这种较重的人造金刚石碳原子排列比碳12同位素金刚石更紧密”。GE的科学家们也描述了人造金刚石的晶体质量,它的质量几乎与硅半导体相匹敌,包括目前已知的一些极少有缺陷的晶体。GE的研究人员首次制成的极小金刚石束它含有要求数量的较重碳原子。为了做到这一点,他们使
Chemists at General Electric Research and Development Center (GE) in Schenectady, New York, USA, make synthetic diamond from carbon that contains excessive amounts of neutrons. GE Chemical Engineer FW Banjozel said: “Natural diamonds typically contain less than 1% carbon 13, which contains 99% of the carbon 13 isotope, and colleagues who completed the analysis, Ford Motor Company H Hogwev said: ”High-resolution X-ray diffractometry measured natural diamond and five GE synthetic diamonds, the heavier synthetic diamond carbon atoms arranged more closely than carbon 12 isotope diamond." GE Scientists also describe the crystalline quality of synthetic diamond and its quality is almost comparable to that of silicon semiconductors, including some of the most infamous crystals known to date.The first diamond made by GE researchers contains the required amount Heavier carbon atoms. In order to do this, they make it
