Design of Reactive Crystallization Fieldto Create Mono-dispersed and Nanosized Crystals
Control of size distribution through precipitation of strontium sulphate and calcium carbonate were performed in a solution containing polyethylenimine (PEI) and water-in-oil (w/o) -microemulsion. The important roles of PEI are the effect of chelation and protective colloid. Nucleation is considered to be controlled by the formation and the decomposition of polymer-cation complex, and crystal growth is considered to be restrained in the polymer-gel network. On the other hand, each microemulsion acts as like a microreactor, therefore, precipitates which have desired crystal size are considered to be possible to obtain nanosized crystals by controlling the size of microemulsion droplet.
