中文摘要：

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,可以在温和的条件下合成金刚石.

英文摘要：

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.
