In this study, the effect of K2HPO4 and KOH on the nucleation kinetics of potassium di hydrogen phosphate (KDP) was investigated. The polythermal method was used for the measurement of the metastable zone width(MZW) and experiments were carried out at three cooling rates. It was found that, additives not measured with concentration, but they increased the solubility and decreased the MZW of KDP. The MZW was sharply decreased by the addition of additive(s) up to 100 ppm concentration to the aqueous solution of KDP.

Key Words: Potassium dihydrogen phosphate; nucleation kinetics; metastable zone width; additives.
