Sample
Name
Water ice spherical particles about 2 to 100 μm at 173 K
Date
2016-10-24
Thickness
6.0 $\pm$ 1.0 $mm$
Diameter
48.0 $mm$
Surface roughness
rough
Sample changes
The sample kept at 173 K under primary vacuum for 18h underwent mostly metamorphism of the ice particles (recrystallisation/sintering, change of grains size and shape). No significant sublimation was seen at the surface.
Substrate material
aluminum sample holder
Substrate comments
Cylindrical 48 mm diameter sample holder with a thickness of 5 mm
Comments
Fresh sample prepared just before the measurement.
