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