Effect of Argon Pressure on the Sublimation Rate of Magnesium

Abstract
The sublimation rate of magnesium in an argon atmosphere
with pressures ranging' from 10- 11 up to 760 mm Hg was measured.
At pressures from 10-6 to 10- 2 mm Hg the sublimation rate is
approximately constant. It considerably decreases at higher pressures.
At pressures of about 102 mm Hg the sublimation rate of
magnesium is very low. As the transfer of vapour from the
surface of the sample to the condenser takes place by diffusion at
higher pressures and by molecular flow at lower pressures, it is
not possible to treat the problem uniformly. The results of the
present experiments are therefore related to some approximative
equations.
