Purity of gypsum

 · Generally Gypsum having purity more than 80% as CaSO4.2H2O is considered suitable for mentaining SO3. If Gypsum having very Low purity can cause high innsoluble residue in cement and decrease the strenght due to high caly content. However high purity of gypsum ~88.0% is ideal.But u should count C3A in cement before deciding SO3 target.

The process by which this synthetic gypsum is created is also known as forced oxidation: CaSO 3 (aq) + 2H 2 O (l) + ½O 2 (g) → CaSO 4 · 2H 2 O (s) A natural alkaline usable to absorb SO 2 is seawater. The SO 2 is absorbed in the water, and when oxygen is added reacts to form sulfate ions SO 4 - and free H +.
