Conclusions
-
1.
The results of determining the evaporation rate in vacuum by the first and second variants coincide with sufficient accuracy.
-
2.
We determined the evaporation rate of graphite brands GMZ, PPG and GÉ in a vacuum of 10−3−10−4 mm and in an argon medium P=760 mm Hg.
-
3.
The evaporation rate of graphite brands GMZ and PPG in the temperature range of 2000–2600°C with an increase of pressure from 10−3−10−4 mm to 760 mm Hg decrease four- to six-fold.
