It is shown that for seeded precipitation, the morphology and the location of active growth sites of the seed crystals depend on the conditions in which they were produced in terms of supersaturation, ion ratio of reactants, and feed rate. Further, the properties of the seed crystals influence the morphology and, hence, the size of the seeded precipitated particles. The reaction system is barium sulfate from barium chloride and potassium sulfate in a semi‐batch stirred tank reactor.
