Beryllium Aluminate, Be(AlO2)2






Ebelmen prepared artificial cymopliane (chrysoberyl), Be(AlO2)2, by fusing the constituent oxides with boric anhydride and calcium carbonate.

Crystals indistinguishable from cymophane result from the solution of alumina and beryllia in fused alkaline sulphides. Hautefeuille and Perrey used a mixture of alumina, beryllia, potassium sulphate, and carbon.
