The change in size of ultrafine monodispersed colloidal particles of basic yttrium carbonate and neodymium normal carbonate with time from solutions of their corresponding salts, respectively, were followed in the presence of urea. Nielsen's chronomal analysis were used to characterize the growth mechanism and to obtain rate constants. Growths of both particles are thought to be one-order polynuclear layer growth mechanism.
