Sintered magnesia comprises particles of grain size greater than 3.35 g/cm<3>, and more than 1.5 wt.% Fe2O3. The amt. of Fe<3+>, calculated as Fe2O3, and auxiliary phase contg. Fe<3+>, e.g. dicalcium ferrite (CF), brown millerite magnesium ferrite (C4AF) and magnesium ferrite (MF), does not exceed 0.5 wt.%. Also claimed are: (i) the prodn. of the sintered magnesia; and (ii) a shaft furnace for carrying out the prodn..
