Abstract 

The effect of temperature, cooling rate and tributy phosphate (TBP) on the metastable zone width (MSZW) of ammonium dihydrogen phosphate (ADP) was investigated in this work. The MSZW and the apparent nucleation order of ADP under different conditions were calculated. The induction time for ADP with and without TBP was determined, and the nucleation parameters were determined using the classical theory of nucleation. The results show that the MSZW decreases with increasing temperature and the presence of TBP leads to an increase in the MSZW, induction time and nucleation parameters.
