The binary diffusion coefficient DAB of subliming C60 in He, N2 and Ar gas has been determined at a gas pressure between 5 and 10 kPa. It resulted DAB/(cm2/s)=Do(Po/Pt(T/To)n as a function of the total pressure Pt of the vapor phase and temperature T. At To=273 K and Po=1.0133×105 Pa, the values Do = (0.059±0.004) cm2/s, (0.011±0.003) cm2/s, (0.012±0.007) cm2/s, n = 1.77±0.06, 2.02±0.18, 1.77±0.37 were obtained for He, N2, Ar and (830-1000) K, (800-1020) K, (875-1095) K, respectively. Only 40 wt% of the initial C60 material yielded reliable DAB where the vapor pressure of C60 followed log10(P/Pa) = -(8976±60)/T/K+(11.05±0.07) for T between 640 and 1055 K. |
