摘要	Experimental measurements of colloidal crystallization in a wide range of volume fractions of charged particles were performed to investigate the liquid-metastable-stable transition process. To fit the obtained experimental data, we developed a theoretical model to formulate the kinetics of the concurrent liquid metastable and metastable stable transitions. This model is well-supported by our observations. We found that when the ratio of the metastable stable transition rate to the liquid metastable rate is very large; the metastable state can become undetectable, although it still exists, offering a possible explanation for very few exceptions to Ostwald's step rule.; Experimental measurements of colloidal crystallization in a wide range of volume fractions of charged particles were performed to investigate the liquid-metastable-stable transition process.
