Preparation of Whitening Dihydrate Gypsum and Short ,
Abstract Using FGD gypsum as the raw material, whitening and large prismatic dihydrate gypsum can be obtained by dissolution-crystallization and decoloring process with α-hemihydrate gypsum whiskers prepared in MgSO 4-CaCl 2-H 2 O solution, which can transform into whitening short columnar α-hemihydrate gypsum
Modiﬁcation of FGD gypsum in hydrothermal mixed salt, This study focused on the conversion of the FGD gypsum into a-hemihydrate calcium sulfate by a , process, temperature was one of the most sensitive
