The self‐setting behavior of α‐calcium sulfate hemihydrate is highly dependent on its morphology that is tuned through the addition of ethanol into CaCl 2 aqueous solutions during a salt solution method. With the increase of the ethanol/water volume ratios, the mean lengths of the formed crystals decreased from 24 to 19 μm, whereas their mean widths increased from 6 to 18 μm. It is also detected that the setting time of α‐ CSH paste reduced from 120 ± 12.3 to 17 ± 2.1 min as the crystal morphology evolved from rod‐like to equiaxial.
