By measurements of loss of weight, checked by water extraction of unreacted salt, it was found that at high temperatures liquid sodium sulfate reacts with mullite more rapidly than with alumina. A study of the structures involved explains this. Nephelite is the principal product of reaction. Experiments indicate that the resistance of high‐alumina firebrick to soda attack can be improved with a refractory coating, particularly one composed of alumina, nephelite, and sodium aluminate.
