Abstract
The effect of iron oxide on direct bonding in chrome .. magnesite refractories was
studied in two series of experiments. In one series purified chromite and pure magnesium
carbonate sintered with different iron oxide additions were used; and in the other a
highgradechromeore and natural magnesite sintered with different iron oxide additions.
It was observed that additions of iron promote direct bond in purified chromite and
magnesia compositions. But with natural chrome ore and magnesite, even with high iron
oxide concentration some amount of silicate phase is necessary to develop direct
chromite-periclase bond.
