The vaporization behavior of multicomponent commercial refractories composed mainly of the system MgO-Al2O3-Cr2O3 was studied at 1600°C in vacuum It is found that the least volatile component in refractories, i.e., Al2O3, CaTiO3 or Mg (Al1-xCrx) 2O4, remained on the surface and made a non-volatile stable surface layer which disturbed diffusion of the more volatile components.<br>The vaporization rate of MgAlCrO4 spinel increased with increasing amount of additives, most pronounced with CaO followed by Fe2O3 and SiO2. Effect of CaO was explained by the formation of a volatile compound 8CaO⋅6Al2O3⋅2CrO3.
