Vacuum Condensing Point와 물질이동에 관한 Sublimatography (III)
Mass Transfer and Vacuum Condensing Point of Sublimatography(III)-Relations among the Characters of Sulfur ion the Sublinato-tube-
We studied on the sublimatographic characters of sulfur as follows;
1） Vacuum condensing point of sulfur at different heating temperature and vacuum degree is obtained.
2） Amount of sublimation of sulfur is determined quantitatively by the sublimatography.
3） The vapor pressure, molar velocity of sublimation and mass transfer coefficient of sulfur are calculated by experimental data as follows:
Ph/Ps =γ （γ=1.03）
Psn/kG （n=0.977）
（γPs）n' = k'G (n'=1.0)
kgav =1.3985×10-2
