The technique for the preparation of polyphase refractories for electron probe investigations is described. Chemical changes occurring during heating of an unused chemically bonded magnesia‐chrome refractory were studied and the spatial distribution of Fe, Cr, Al, Mg, Ca, and Si at different temperatures was determined. The development of the reaction layer around the chromite grains, the migration of ions into the periclase grains, and the distribution of ions in silicates were followed qualitatively using Kα X‐ray and electron back‐scattering displays.
