Induction periods have been measured for various supersaturated aqueous solutions of ammonium dihydrogen phosphate doped with ammonium sulfate and potassium sulfate by the direct vision method. Various critical nucleation parameters have been calculated based on classical theory for homogeneous nucleation and discussed. The critical nucleation parameters increase with the increasein concentration of doping.
