Sample of water ice spherical particles 4.5±2.5 μm at 173 K after measurement in the CarboNIR thermal vacuum chamber

Physical characteristics

Thickness: 3.0 $\pm$ 1.0 $mm$
Diameter: 48.0 $mm$
Surface roughness: smooth
Sample changes: The sample kept at 173 K under primary vacuum for 48h underwent slight sublimation (of the top ~0.5mm) and mostly metamorphism of the ice particles (recrystallisation/sintering, change of grains size and shape)
Substrate material: aluminum sample holder
Substrate comments: Cylindrical 48 mm diameter sample holder with a thickness of 1 mm
Comments: Fresh sample prepared just before the measurement.

Sample environment: Temperature

Temperature: 173.0 $K$
Time at T: 48.0 $h$
Temperature max: 173.0 $K$
Comments: The sample was kept at constant temperature of 173 K

Sample environment: Fluid

Type: vacuum
Fluid temperature: 173.0 $K$
Fluid pressure: 6.0 $\pm$ 1.0 $mbar$
Comments: The sample was kept under constant primary vacuum, of less than 7.2 mbar
