Abstract

PURPOSE: When α-type gypsum hemihydrate is produced directly from the sulfur oxide in the waste gas, it is made to produce selectively needle-like crystals or prismatic crystals alone whether by addition such mineralizing agent as metallic salt, if necessary, or by combination of these and to produce at the same time α-type gypsum hemi-hydrate economically in large scale.
