Sustainable Pathways for the Synthesis of Calcium Sulfate Hemihydrate

open access: yesAngewandte Chemie International Edition, Volume 64, Issue 20, May 12, 2025.
Calcium sulfate hemihydrate (bassanite) plays a key role in construction as a hydraulic binder. Due to its instability in water, industrial production primarily relies on thermal dehydration of gypsum. This review examines alternative, potentially more sustainable methods for the synthesis of bassanite, including gypsum conversion at lower temperatures
