Abstract

Micronized BaSO₄ particles with a narrow size distribution were produced by using a double-jet reactive crystallizer. Polyethylenimine (PEI) acted as a growth/agglomeration inhibitor at a high PEI dosage, hence the particle size and size distribution width decreased, and BaSO₄ crystals with the desired qualities were obtained. Similar results were obtained in previous studies in which of SrSO₄ and PbSO₄. We believe that our method, which involves the use of PEI, can be employed for the production of various inorganic sulfates in which the particles have a monodisperse size distribution.
