The System MgO‐ZnO‐SiO2

The system MgO-ZnO-Sio2 was studied by the quenching technique. No ternary compounds were found in the system, but extensive solid solution relations occurred in the magnesiumand zinc-bearing compounds. Two ternary eutectics and one reaction point were located; the minimum melting point in the system was 1370°± 5°C at a composition of 15.5 wt% MgO, 37.0 wt% ZnO, and 47.5 wt% SiO2.
