Abstract: In this paper, the characteristics and the distribution of anhydrite resources in our country were introduced. At the same time, the activity of excitation and chemical modification techniques about anhydrite were also discussed. Some new technical characteristics on preparing sulfuric acid, new cementing materials and reinforcing polymer by using anhydrite were analyzed. The application prospect of anhydrite in cement, plastering gypsum and self-leveling materials was summarized. In combination with the features and application requirements of anhydrite, the specific direction in deep-level development of anhydrite was pointed out.
