Hydration / dehydration cycles of salt hydrates : studied with NMR
conference paper
A heat buffer is the missing link for introduction of renewable energy on a large scale. Salt hydrates are a promising technique to fulfill this task. In this study, we focused on reversibility of sulfate hydrates dehydration/hydration cycles. Different hydrates are studied with TGA and Nuclear Magnetic Resonance (NMR). Two hydrates were selected to perform cyclic experiments: CuSO4 and MgSO4. Several heating and cooling cycles are followed with help of NMR. Pore water was only observed during the first dehydration cycle.
