Abstract
Dehydration of brucite was measured by means of high-pressure differential thermal analysis (HP-DTA). The enthalpy of the dehydration was derived as a function of temperature and pressure from thermodynamic quantities of brucite, periclase, and H2O fluid. The dehydration of brucite is likely to be used to quantify an HP-DTA system up to 6GPa. The system calibration factor was determined to be 1.2×10-3JK-1s-1.
