Reactive crystallization is known to produce very high levels of supersaturation. When supersaturation of a crystallizing compound is created by chemical reaction, the operation is known as reactive crystallization. In reactive crystallization, reactions can be very fast compared to the mass transfer rates and growth rates to the crystals.
