The preparation of hemihydrate gypsum crystals with different morphologies by using additives has attracted much attention. Recent research work on the use of organic, inorganic and composite additives to control the growth of hemihydrate gypsum crystals into fibrous gypsum whiskers or short columnar high-strength α gypsum was summarized. The regulation mechanism of organic and inorganic additives on the nucleation and growth process of hemihydrate gypsum crystals was represented. Some problems that need to be further studied in this field were analyzed. This review can provide a reference for the crystal growth control of hemihydrate gypsum crystals and similar crystal materials.
