WebPreparing α-hemihydrate gypsum (α-HH) from phosphogypsum (PG) in electrolyte solution and atmospheric pressure has been developed as an energy-efficient and profitable method to dispose PG, which can alleviate its environmental contamination and reduce the use of natural gypsum. WebThe objectives of this study were (i) to isolate and characterize mannitol hydrate, and (ii) to solve its crystal structure from high-resolution synchrotron X-ray powder diffraction data. …
