AIM: To study the effects of presintering temperature and the temperature elevation speed on the physical and mechanical properties of alumina glass composites (AGC).

Soderberg electrode is the one of the critical technologies for large-scaled electric phosphorus furnace. The electrode consumption of unit product is much lower than that of pre-sintering electrode.

Three series of experiments were carried out to observe the effects of composition, presintering schedule, particle size of fe powders, compacting pressure, sintering time and hot-pressing.
