摘要：

Diamond was synthesized by the reaction of potassium and sodium carbonate at 2 GPa and 500 degrees C 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.
