The Metastable Zone of aqueous solutions
Journal Title: CHEMIK nauka-technika-rynek - Year 2014, Vol 68, Issue 3
Abstract
The Metastable Zone (MSZ) is one of the most essential notions in industrial crystallization. However, its definitions have still some vagueness, and models to estimate the metastable limit (MSL) have not been matured enough to be used in practical operation. This paper presents the results of studies of determination the nucleation point and the MSZW of potassium chloride, potassium nitrate (V) and potassium sulphate (VI) solutions, using the Reaction Calorimeter Mettler Toledo RCle.
