Investigation of the Precipitation of Barium Sulfate …

In the present work, barium sulfate particles were produced by discontinuous precipitation in a stirred tank reactor. Particle sizes of less than 100 nm were achieved. Particle size distributions strongly depend on the mechanical mixing and the molar ratio of the reactants as well as on the stabilization of the particles in the suspension.

Barium sulfate

Barium sulfate (or sulphate) is the inorganic compound with the chemical formula BaSO4. It is a white crystalline solid that is odorless and insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. Its opaque white appearance and its high density are exploited in its main applications.
