摘　　要：探讨了用硫酸镁和纯碱制备透明碳酸镁的适宜工艺．通过正交实验，研究了反应温度、反应时间、浓度比和热解温度等因素对产品的影响，并得到了实验条件的最优组合．产品与天然橡胶混炼后的折光率与天然橡胶相同，红外光谱图和电镜测试符合要求．The technology of preparation of transparency magnesium carbonate by the reaction of magnesium sulfate with sodium carbonate is described in this paper.The effect of reaction temperature,reaction time,ratio of concentration,thermolysis temperature and so forth on transparency magnesium carbonate is studied by using orthogonal designation.The best arrangement of the experimental conditions is obtained.After mixing transparency magnesium carbonate with gum rubber,the refractive index of gum rubber is not changed.The tests of infrared spectra and electron microscope accord with the demands.
