Beside its family of well known dihydrate processes..., over the last twenty five years PRAYON has developed a dihydrate-hemihydrate process that produces merchant grade calcium sulfate together with 36% P205 acid. As the calcium sulfate is obtained as wet alpha-hemihydrate, it contains very little water and, if allowed to cure, will naturally rehydrate by combining with its free moisture to produce a "selfdried" gypsum. 1, record 1, English, - alpha%20hemihydrate
