The dissolution of CaO and the formation of Mg2Ca were detected with in situ synchrotron radiation diffraction. The dissolution of CaO was observed at ∼407 °C with the detection of a peak unique to the Mg2Ca phase prior to melting of Mg. After the solidification no CaO was detected, and Mg2Ca and MgO phases were observed.
