摘要：
Growth rates of silicalite-1 in combination with thermodynamic aspects of the aqueous chemistry of silica are used to evaluate two zeolite growth models. Analysis of a nanoparticle growth model indicates that, in its current state, the model does not adequately predict the effect of ionic strength and pH on growth rates. Preliminary studies of a monomer addition model based on solution chemistry, indicate the model is capable of quantitatively calculating growth rates as a function of temperature, pH, silica concentration, and ionic strength.
