| Abstract: | Calcium sulfate whiskers were prepared by hydrothermal synthesis with gypsum as materials, the effect of coneentration of raw materials, the temperature, the time and pH on the aspect ratio of product were studied. The optimum conditions for the preparation were that the reaction temperature is 130℃, initial pH value of slurry is 10, mass fraction is 3% and the time is 9 hours, as a result of microscope to mensurate the aspect ratio of calcium sulfate whiskers. Under these conditions, the aspect ratio of calcium sulfate whiskers is 75. |
