DSC study of melting and solidification of salt hydrates

Conference ·
OSTI ID:6525473
Most salt hydrates expecially those proposed for thermal-energy-storage applications, melt incongruently. In static systems, this property often leads to differences between the enthalpy of fusion and enthalpy of solidification. By means of differential scanning calorimetry (DSC), these differences have been determined for several salt hydrates. The hydrates studied include Na/sub 2/SO/sub 4/.10H/sub 2/O, Na/sub 4/P/sub 2/O/sub 7/.10H/sub 2/O, Mg(NO/sub 3/)/sub 2/.6H/sub 2/O, MgCl/sub 2/.6H/sub 2/O, CuSO/sub 4/.5H/sub 2/O, and Na/sub 2/B/sub 4/O/sub 7/.10H/sub 2/O.
