Abstract

The objective of the present study is to examine the behaviour of metal condensation, including intensive condensation, far from equilibrium. In the present experiment, highly accurate measurements of condensation rate, condenser surface temperature and vapour pressure were rendered possible. In addition to the techniques for these measurements, the vacuum distillation method was utilized to ensure that the results were not affected by the presence of non-condensable gases. In addition, the conformity in the vapour flow field of the present experiment to the analysis to be compared was also assured.
Measurements were made for a vapour temperature range from 553 К (23 Pa) to 633 К (223 Pa). It was found that the present results which were thought to provide the most reliable data for condensation of a metal are in agreement with the recent analytical study of Labuntsov and Kryukov, and that the condensation coefficient of metal is very close to unity.
