Sažetak
The mechanisms controlling the growth rate of electrolyte crystals precipitating from aqueous solution may be classified in eight types. Most of these are associated with a specific kinetics- linear, parabolic or exponential, - and composites of these kinetics are also found. A linear kinetics is found when the crystal grows by a rate controlled by the transport through the solution or the adsorption at unspecified positions at the crystal surface. Parabolic and exponential kinetics indicate that the growth rate is controlled by the integration at kinks with a rate determined by the cation dehydration frequency. The theory agrees satisfactorily with the empirical growth rates.
