Rearrangement of conodes of the phase diagram of the MgO-Al2O3-SiO2 system and its technological prospects

The subsolidus structure of the phase diagram of the MgO - Al₂O₃ -SiO₂ system is studied and the boundaries of the domains of existence and the probability of the existence of all stable phases in the entire temperature region are determined. The temperature of the pseudobinary spinel — mullite eutectic is refined. The results are taken into consideration in constructing the corresponding nonisothermal section of the phase diagram, which opens new technological possibilities due to the rearrangement of the conodes of the MgO -Al₂O₃ - SiO₂ system.Translated from Ogneupory i Tekhnicheskaya Keramika, No. 11, pp. 4 – 8, November, 1996.
