Molten cast materials of the Al2O3-MgO system

Molten cast alumomagnesia refractory materials containing up to 28.3% MgO (MgAl2O4) are investigated. It is shown that materials with 10–15% MgO have a complex structure and phase composition. The latter can be interpreted as a solid solution of corundum and spinel or as a combination of MgO · 2.5Al2O3. The behavior of these materials in molten TK16 and K8 glass is investigated.
