Abstract:
The flue-gas desulfurization gypsum (FGD gypsum) from Mae Moh power station is characterized for its physical and chemical properties, precleaned by acid leaching and sedimentation to light coloured powder which is later used, in later used, in comparison with natural gypsum, as raw material for the syntheses of [beta]-hemihydrate, anhydrites and multiphase plasters. Based on the commercial specification, these gypsum plasters are fabricated into product, i.e. gypsum board and projection plaster slurry. With the employment of gypsum technology, the product performance can be engineered to match up to that of the natural gypsum.
