Examples
Embodiment 1
[0076] Put the dried graphite powder into the reactor, pass pure NF 3 Gas, the pressure reaches 150KPa. Raise the temperature, maintain the reaction temperature at 450° C., and react for 30 hours. The product was taken out after cooling, the fluorocarbon ratio of the product was 0.48, and the yield was 92%. The infrared absorption spectrum and elemental analysis EDS spectrum of the product are as follows figure 2 and image 3 shown.
Embodiment 2
[0078] Put the dried graphite powder into the reactor, pass pure NF 3 Gas, the pressure reaches 150KPa. Raise the temperature, maintain the reaction temperature at 540°C, and react for 15 hours. The product was taken out after cooling, the fluorocarbon ratio of the product was 0.95, and the yield was 87%. The infrared absorption spectrum and elemental analysis EDS spectrum of the product are as follows Figure 4 and Figure 5 shown.
Embodiment 3
[0080] Put the dried graphite powder into the reactor, pass pure NF 3 Gas, the pressure reaches 100KPa. Raise the temperature, maintain the reaction temperature at 640°C, and react for 4 hours. The product was taken out after cooling, the fluorocarbon ratio of the product was 1.12, and the yield was 55%. The infrared absorption spectrum and elemental analysis EDS spectrum of the product are as follows Figure 6 and Figure 7 shown.
