A measurement method for determination of the metastable zone width based o
n a natural cooling was presented. The method was used for determination of
the maximum supersaturation Deltac(max) for aqueous solutions of three ino
rganic salts: AIK(SO4)(2). 12H(2)O, K2SO4 and KNO3 at different turbine agi
tator's regimes. A comparison between the experimental results and data obt
ained by Synowiec's and Mers-mann's calculation methods was performed.
