Feb 07, 2014 Furthermore, it leads to separation of layer-forming zinc compounds (e.g. zinc borate) at hotspots (fouling at fuel assemblies) and/or the crystallization of zinc corrosion products out of the coolant in hot areas [HOF10]. This in turn causes a decrease of pH-value and, consequently, an increase of the corrosiveness of the coolant flow.

Reactive crystallization in pharma industry - Longdom

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.
