| 摘 要： | 以金属钾和碳酸钠为反应原料, 在压力为2 GPa, 温度为500 ℃的密封白金坩埚中反应18 h, 所得产物通过粉末X射线衍射和显微拉曼分析进行了表征, 证实合成出了微米级的金刚石. 对金刚石的合成机理进行了研究, 推测其反应过程为碳酸钠在铂和钾的作用下分解出CO2, CO2与钾反应得到金刚石. 研究结果表明金刚石可以在温和的条件下合成.

| Abstract: | Diamond was synthesized by the reaction of potassium and sodium carbonate at 2 GPa and 500 ℃ for 18 h. The final product was characterized by powder X-ray diffraction and Raman spectroscopy, which confirmed the existence of micrometer-sized diamond. A probable reaction mechanism was discussed that Na2CO3 reacted with Pt and K under high pressure and high temperature to generate CO2 which reacted with K to produce diamond. The results show that diamond can be obtained under mild conditions of pressure and temperature. |
