Conclusions We determined the creep at high temperatures and under compressive loads of fused periclase, periclase, and magnesia-spinel articles based on fused and sintered materials. For specimens of fused periclase with a dense, coarsely crystalline structure and low concentrations of silicate phases, there is typical a low level of creep; the decisive mechanism of deformation in such materials is, apparently, diffusion-viscous flow and slippage across the grain boundaries. In granular periclase and magnesia-spinel refractories with a porous structure and a comparatively high content of silicates, the deformation rate is significant, and the decisive mechanism of deformation for these materials is probably viscous flow of intercrystallite substance.
