Stability of colloidal silica I. Effect of simple
The stability of colloidal silica sols (Ludox HS and Ludox AM) in the presence of various concentrations of NaCl LiCl KCl CsCl NaBr NaI CaCl 2 and Ca(NO 3) 2 has been studied as a function of pH. With increasing pH the stability of the silica sols towards electrolytes markedly decreases except for KCl and CsCl which show a minimum in stability at intermediate pH values.
