Synthesis of α-hemihydrate gypsum from cleaner

10/09/2018· Phosphogypsum (PG), as a waste by-product with high content and complicated impurities, is difficult to be utilised effectively. Herein, cleaner PG is prepared with “HCl H 2 SO 4 method”, and thus is used to synthesise α-hemihydrate gypsum (α-HH) in CaCl 2 solution under atmospheric pressure. Morphology and mechanical strength are controlled by introducing varying dosages of modifier (0

Distribution behavior of arsenate into α-calcium sulfate

01/09/2020· Transforming gypsum into α-calcium sulfate hemihydrate (α-HH) provides a promising utilization pathway for the abundant amount of chemical gypsum. The transformation follows the route of “dissolution-recrystallization”, during which the arsenic pollutant in gypsum is released into the solution, and hence raises the possibility of being distributed into the product of α-HH, a potential
