Morphology Control and Self-Setting Modification of [alpha]-Calcium Sulfate Hemihydrate Bone Cement by Addition of Ethanol

The self-setting behavior of [alpha]-calcium sulfate hemihydrate is highly dependent on its morphology that is tuned through the addition of ethanol into CaCl2 aqueous solutions during a salt solution method. With the increase of the ethanol/water volume ratios, the mean lengths of the formed crysta...

Description
Summary:The self-setting behavior of [alpha]-calcium sulfate hemihydrate is highly dependent on its morphology that is tuned through the addition of ethanol into CaCl2 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 [alpha]-CSH paste reduced from 120 ± 12.3 to 17 ± 2.1 min as the crystal morphology evolved from rod-like to equiaxial. [PUBLICATION ABSTRACT]
