N2  - The equilibrium phases of the BeSO4-H2O system were studied by vapour hydration of BeSO4 and equilibration of thermally produced mixtures. Tetra-, di-, and mono-hydrate are the stable hydrates with no solid solution regions between them. X-ray and infrared spectra are presented for these hydrates and a provisional phase diagram drawn.    Reversible transitions of BeS04 were found at 588&#176; and 639&#176;, the latter showing a hysteresis splitting of 4&#176; on cooling. Transition heats of 1.2 &#177; 0.1 and 0.5 &#177; 0.1 kcal/mole respectively were found by differential thermal analysis.
