- Description
- Compact slabs of salty (MgSO4) ice are produced by slowly freezing small volumes of salt solutions into a laboratory freezer at 230K. The samples are then introduced in the SCITEAS-2 simulations chamber and their slow sublimation at low temperature and in secondary vacuum is followed for several tens of hours by VIS-NIR hyperspectral imaging.
