Effect of MgO Grain Size on Thermal Expansion Behavior of Alumina-Magnesia-Carbon Refractory

The effect of MgO grain size on the permanent linear change behavior of resin bonded alumina–magnesia–carbon refractory has been studied in relation to the formation of spinel phase in these refractories as a function of firing time and temperature. From scanning electron microscopic studies, spinel...

Summary:The effect of MgO grain size on the permanent linear change behavior of resin bonded alumina–magnesia–carbon refractory has been studied in relation to the formation of spinel phase in these refractories as a function of firing time and temperature. From scanning electron microscopic studies, spinelization at the interface of Al2O3 and MgO grains has also been studied to determine the reaction kinetics for gaining insight into the process.
