The mechanism of calcium sulphate alpha-hemihydrate formation from gypsum by this method has not yet been well studied and verified. Some information suggests that the reaction evolves in the solid phase. Water molecules slowly diffuse in drops from dihydrate interlayers (solids-state mechanism of the reaction). Others state that the reaction evolves in the solution, i.e. it is proceeded by ...
