베릴륨 황산염, 테트라수화물

Beryllium sulfate may be prepared by treating an aqueous solution of any beryllium salt with sulfuric acid, followed by evaporation of the solution and crystallization. The hydrated product may be converted to anhydrous salt by heating at 400°C. The anhydrate may also be prepared by reacting the oxide with SO2 gas at elevated temperature. Its CAS number is 13510-49-1. If the solution method is used, a tetrahydrate forms, (BeOH)2SO4·4H2O whose molecular weight is 177.1462 g/mol with a CAS number of 7787-56-6. No major commercial application of berylliumsulfate is known and it has not been offered for sale.
