摘　　要：湿法磷酸副产的磷石膏具有一定的应用价值,但其中的杂质影响了下游制品的质量,限制了它的应用途径及数量。在研究磷石膏回收副产石膏粉的基础上,分析比较了采用晶型转化生产的石膏粉和高温煅烧副产的石膏粉的物理指标,以求拓宽其综合利用的途径。Phosphogypsum as the by⁃product from wet⁃process phosphoric acid production offers certain value of application.However,the contained im⁃purities may affect the quality of downstream products,and thus limits its applications and quantity.Based on the research of phosphogypsum recovery to product gypsum powder,the physical parameters of using crystal phase transformation is compared to produce gypsum powder,and high⁃temperature calci⁃nation to product gypsum powder,so as to expand its comprehensive utilizations.
