Liquidus of MgO and MgAl2O4 in the CaO‐MgO‐Al2O3 System at 1550 and 1600°C

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT In this study, the liquidus of MgO and MgAl2O4 spinel phase in the CaO‐MgO‐Al2O3 system at 1550 and 1600°C were experimentally investigated using a classical quenching method. In order to examine the liquidus composition accurately, the equilibration was carried out using four different ways using the combinations of Pt and ceramic (MgO and ...
