Samples Containing Beryllium

Beryllium oxide finds useful applications in refractory crucibles because of its high melting point (2570 °C) and good resistance to thermal shock. BeO is insoluble in dilute HCl but can be put into solution by boiling with nitric HF or sulfuric acids or by fusion with potassium bisulfate and dissolution of the fuseate in acidified water.
