Study on Preparation of Calcium Sulfate Whiskers by Gypsum

CUI Yi-shun,LIU Yong,FU Ling-jie,LIU Fei(School of Material and Chemical Engineering,Sichuan University of Science & Engineering,Zigong 643000,China)  
Calcium sulfate whiskers were prepared by hydrothermal synthesis with gypsum as materials.the effect of concentration 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.
