Synthesis of metal oxide particles from aqueous media: The homogeneous alkalinization method

An analysis of the urea method as a way to synthesize uniform colloidal particles is presented. Various selected cases of precipitation and coprecipitation are reviewed to illustrate the inherent complexities of the method. The importance of the kinetics of urea hydrolysis is recognized. The concept...
