Quenching of Na2SO4 - CaSO4 melts down to room temperature results in different forms of metastable solid solutions dependent on the CaSO4 content. The transformation of these solid solutions into stable phases were investigated after various times and temperatures by X-ray powder diffraction and thermal analyses. An equilibrium phase diagram is derived, which is in accordance with all experimental facts.
