One of the important sources of refractory material in Egypt is alunite, a hydrated potassium aluminum sulfate. The reaction occurring on heating this material is studied by X‐ray and thermal‐analysis methods. If the potash is leveled out after a preliminary calcination, corundum or mullite brick may be produced from the resultant material.
