The recently published points of zero charge of metal oxides and related materials are compiled to update the previous compilation (Kosmulski, M., "Chemical properties of materials surfaces." Dekker, New York, 2001). The purity of materials is the most important factor responsible for discrepancies
Electrokinetic measurements and potentiometric titrations of indium oxide (commercially available reagent grade powder, washed with NaOH and HNO(3) to remove strongly adsorbed species) indicate the pristine point of zero charge to be pH 8.7. The isoelectric point at pH 9 was obtained for gallium oxi
