The reaction between alkali vapor and the theoretical composition MgAl2O4
The theoretical composition was made from MgO-rich MgAl2O4 (MR66) and alumina powder.The static crucible method was used to study alkali-resistance of the block samples.It has been observed that alkali steam permeated into the hole and reacted with corundum particles that produced β-Al2O3 by means of XRD,SEM and EDS.It led to volume expansion,cracks and melting erosion of corundum particles.The specimen of the 32% content of MgO has good physical and chemical properties and excellent alkali erosion performance.So the specimen is suitable for oxy-fuel combustion for glass melting furnace.
