Ternary System Al_2O_3-MgO-CaO: I, Primary Phase Field of Crystallization of Spinel in the Subsystem MgAl_2O_4-CaAl_4O_7-CaO-MgO

摘要

Using a novel experimental procedure in the field of ceram- ics/materials science that is based on the precise microanal- ysis (scanning electron microscopy, coupled with wave- length-dispersive spectroscopy) of the phases that are present in equilibrated specimens, the solid-state compat- ibility relations in the subsystem MgAl_2O_4-CaAl_4O_7-CaO- MgO and the melting relationships in the subsystems MgAl_2O_4-CaAl_2O_4-MgO and MgAl_2O_4-CaAl_2O_4- CaAl_4O_7 were established.
