Popis:	The conducted tests showed that low-silica periclase-spinellide refractories having an excess iron content in the chromium-containing component are not suitable for use because of their rapid slag-induced chemical corrosion. In continuously operating metallurgical units where splitting of the lining due to the action of the slags is not a decisive factor, it is advisable to use refractories having the optimum content of iron oxides for the formation of a homogeneous spinellide matrix. In units operating cyclically under the most severe conditions (for example, in the ASEA-SKF type installations), the periclase-spinellide products in which the spinellide having the minimum content of iron oxides acts as a fused synthetic chromium-containing component are suitable since they exhibit the best high-temperature thermomechanical properties and stability.
