日前,郑州大学单崇新教授团队卢英杰博士等人合成出质量1.2克拉以上、颜色优白级、净度SI1级的高品相钻石。据悉,钻石是指经过精加工的金刚石,地球上的天然钻石是碳元素在地球深部高温高压的特殊条件下(地表以下100~300 km,压强5×10~9~7×10~9Pa,温度1 200~1 800℃)以及一定含量及比率的铁族金属和石墨或碳条件下历经亿万年的“修炼”而成的,再遇有火山爆发或其他地质运动被带到地表附近。
A few days ago, Professor Lu Yingjie from the team of Professor Shan Chongxin of Zhengzhou University synthesized high quality diamonds with a mass of more than 1.2 carats, excellent white color and clarity of SI1 grade. It is reported that diamonds are processed diamonds, the Earth’s natural diamonds are carbon under the special conditions of the Earth’s deep high temperature and high pressure (below the surface 100 ~ 300 km, pressure 5 × 10 ~ 9 ~ 7 × 10 ~ 9Pa, temperature 1 200 ~ 1 800 ℃) and a certain content and ratio of iron group metal and graphite or carbon under millions of years after the “practice” made, and in case of volcanic eruptions or other geological movement was brought to near the surface .
