| Abstract: | The growth of CuSO4 crystals from a nonaqueous solvent, composed of (NH4)2SO4 and H2SO4 is described. Solubility of CuSO4 in solvents of varying (NH4)2SO4 to H2SO4 ratio, at 200 °C, has been determined, as well as the temperature dependence of the solubility in 0.35(NH4)2SO4 — 0.65H2SO4. Single crystal specimens, weighing up to 150 mg have been obtained. |
