Crystals of strontium sulfate were precipitated in a solution of polyethylenimine (PEI) using a double-jet crystallizer. PEI, as a crystal growth modifier, controlled both the nucleation rate and the growth rate, and enabled to produce fine monodispersed crystals. Both acetic acid and hydrochloric acid were used as a pH-controlling agent. Especially, in case of using hydrochloric acid, highly monodispersed crystals (coefficient of variation, C.V.□ 0.1) were produced within fairy wide operation conditions.
