The aim of this work is to study NaCl samples using thermal analyses in the powder form and single crystal NaCl ingot and to describe the processes that occur in the samples during their thermal treatment. Further, the effect of grain size in NaCl powder samples, the effect of purity and moisture content on its behavior under thermal treatment was characterized. The samples were studied by thermal analyses including non-isothermal differential scanning calorimetry (DSC), thermogravimetry (TGA), thermomechanical analysis (TMA), mass spectrometry (MS), and optical stereomicroscopy (OM). The TMA showed that the smaller the grain size, the earlier the grains are densified and subsequently sintered when heated. On the other hand, the influence of NaCl powder grain size distribution on the course of the TMA curves was recorded and showed a significant influence on the sintering effect.
