Abstract
The metastable zone width studies were carried out for various temperatures for supersaturated aqueous solutions of various inorganic materials K2SO4, Na2CrO4·4H2O, CuSO4·5H2O, NaBr·2H2O, NH4Cl, KNO2, NH4NO3, NaNO3 with pure and EDTA added solutions. The various factors affecting the metastable zone width are discussed and the critical nucleation parameters are calculated. The effect of temperature, chelating agent and the concentration of the solution are discussed.
本文探討許多水溶液系統成核，包括K2SO4, Na2CrO4‧4H2O, CuSO4‧5H2O, NaBr‧2H2O, NH4Cl, KNO2, NH4NO3, NaNO3, 介穩區受EDTA的影響。同時討論影響介穩區的因子，並計算成核參數。尤其，螯合劑、溫度及濃度的效應也一併討論。
