Abstract
SummaryA method of preparing compositions suitable for phase equilibrium studies in systems containing CaO-MgO-Al2O3-SiO2-Fe-O2-Na2O employing a gelling technique is described. The subsolidus assemblages obtained from the recrystallization of some of these gels and from the recrystallization of devitrified glasses of the same composition are compared. It is not yet clear whether either starting material has any advantage as the gels may retain early formed metastable phases and the glasses may fail to nucleate stable phases.
