barium sulphate precipitation
The reaction of barium (Ba 2+) and sulphate ions into barium sulphate (BaSO 4) is [20, 24, 25] In general, a precipitation process is described by processes that include the creation of a supersaturation level followed by the generation of nuclei (nucleation) and the subsequent growth [ 8 ].

Barium sulphate is not self-inflammable as nanometer-sized powder. Also as a mixture with air (dust) under the influence of an ignition source, barium sulphate is not inflammable, so there is no possibility of a dust explosion.
If sulfate must be further reduced ("polished"), an add-on process such as barium, CESR, or SAVMIN is recommended. As a polishing step for sulfate removal, barium salts can be added to precipitate barium sulfate, which has a very low solubility in water, with the final sulfate concentration limited only by the amount of barium added and …
