| 摘 要： | 以盐泥和硫酸为原料，采用常压酸化法制备硫酸钙晶须。考察反应温度、反应时间、搅拌速度、原料配比等因素对硫酸钙晶须的影响。通过实验得出优化工艺条件为：反应温度80℃，反应时间30min，搅拌速度150r／min，原料配比（盐泥、硫酸、水的质量比）1：1．84：2。在该条件下，晶须产率为33．28％，晶须平均长径比为85，白度为68．4％，硫酸钙纯度达到92．75％。

| Abstract: | Calcium sulfate whiskers are prepared by atmospheric acidification method with salt deposit and sulfuric acid as raw materials. Effects of reaction temperature, reaction time, stirring speed, and mass ratio of raw materials on calcium sul- fate whiskers are investigated. By experiment, the optimized process conditions are obtained as follows：reaction temperature is 80℃ ,the reaction time is 30 min, stirring speed is 150r/min, mass ratio of raw materials （ie. salt deposit to sulfuric acid to water） is 1：1.84：2. Under these conditions,yield of whiskers reaches 33.28% ,average aspect ratio of whiskers is 85,white content is 68.4% ,and purity of calcium sulfate reaches 92.75%. |
