WebFluorination of graphite oxide starts at room temperature, however, the main reaction is dehydration of graphite oxide at this temperature. When fluorination temperature was raised to around 100 °C, fluorinated graphite oxide showed a strong (001) diffraction line at about 10 ° in 2θ (Cu–Kα), i.e. ca 0.88 nm as shown in Fig. 9, which supports a Stage 2 … WebAbstract. The ablation of high-purity graphite in oxygen and air atmospheres was studied in the 1000–1400°C temperature range, gas pressures of 2–19 torr and flow rates of 7.6×10 18 to 3.6×10 20 atoms/sec. Gas diffusion effects were eliminated by the use of small samples and fast flow-rates. Very fast ablation rates were observed.
