Abstract Calcium sulphate whisker was prepared by hydrothermal method using seawater or brine as raw material. The effects of the concentration of calcium sulphate,reaction temperature,stirring speed and pH value on the content of calcium sulfate hemihydrate were studied and the optimum conditions were de- termined: the concentration of calcium sulphate was 8% ,reaction temperature was 130 �� ,stirring speed was 150 r /min and pH value of medium was 7. The structure of calcium sulphate whisker was analyzed by polarizing microscope,scanning electron microscopy and X-ray diffractometer. The results show that calcium sulphate whisker has good morphology.
