## Abstract This study presents an evaluation of a new method, called zero growth activation free energy, used to determine the metastable zone width for the secondary nucleation case. It predicts the metastable zone width with a maximum error of 5β10%. Estimation of the metastable zone width for d

The metastable zone width of boric acid in aqueous solutions was measured in the presence of Ca +2 , Mg +2 , Cr +3 , Fe +2 ions. For the measurements of metastable zone width, the polythermal method was used. The impurity concentration is varied from 0 to 1000 ppm in each aqueous solution. It was fo
