Magnesium Oxide - an overview | ScienceDirect Topics

MgO exhibits different properties depending on the source and calcination conditions used during its production. The main parameters used to assess the characteristics of MgO are its reactivity, SSA, crystallite size, crystal structure, density, agglomeration ratio (i.e., the ratio of the primary particle size to the crystallite size), pore structure, total porosity, and morphology (Li, 2013

METHOD AND APPARATUS FOR PRESSURIZED

The dehydration or calcination of raw gypsum to calcium sulfate hemihydrate can be represented by the following formula: CaSO 4.2H 2 O+heat→CaSO 4.½H 2 O+3/2H 2 O. Calcination is the process where calcium sulfate dihydrate is converted to hemi-hydrate, soluble anhydrite, and/or insoluble anhydrite.
