The porosity and strength of specimens of fused MgO obtained by induction smelting in cold crucibles and having ≤1% impurities is significantly increased by the addition of 1% CeO2, 5% ZrO2, and 20% of the vibromilled component plus 5% Y2O3. An addition of 5% Y2O3 has the greatest effect on the sintering characteristics of the MgO·Al2O3 specimens. A significant improvement in the characteristics of the materials is observed with an increase in the pressing pressure of the specimens from 100 to 200 MPa.
