With the continuous development of China's industry,a large amount of desulphurization gypsum has been pro-duced.At present,although the current comprehensive utilization of desulfurization gypsum is increasing year by year,its utilization rate is decreasing,and it is indispensable to explore the high-value utilization path of desulfurization gypsum.One of the ways to resource utilization of desulfurization gypsum is to dehydrate and convert it into α-hemihydrate gypsum.Using desulfurization gypsum to prepare high-performance and high-value-added α-hemihydrate gypsum can reduce the en-vironmental pollution caused by gypsum accumulation,reduce the mining of natural gypsum and bring new economic ben-efits.Based on this,the current research status of the methods of preparing α-hemihydrate gypsum from desulphurization gypsum at home and abroad and its influencing factors were systematically reviewed,its production process path and its ap-plications were summarized,and the prospect of promoting the reduction and resource utilization of desulfurization gypsum were put forward,aiming to improve the utilization rate of solid waste and promote"carbon neutrality and carbon emission reduction".
