Magnesium aluminate spinel (MgAl2O4) is an excellent refractory oxide of immense
technological importance as a structural ceramic. It possesses useful physical, chemical and
thermal properties, both at normal and elevated temperatures. It melts congruently at 2135°C,
shows high resistance to attack by most of the acids and alkalis and has low electrical losses.
Due to these desirable properties, it has a wide range of application in structural, chemical,
