• Initial stages of a native oxidation on Zn_3P_2 by anodization have been investigated for the first time using 3% tartaric acid/propylene glycol electrolyte. A constant-current anodization is found to be superior to a constant-voltage anodization because of the rapid growth of the initial stage in the constant-voltage mode in view of controlling thin oxide layers. The surface composition of anodized Zn_3P_2 was examined by AES and XPS. The oxide layer was identified as a mixture of ZnO, P_2O_5, and P_2O_3: the increased [P_2O_5+P_2O_3]/[ZnO] ratio of 〜 1.3 was obtained at acidic and basic pH values, whereas the composition ratio was 〜 0.2 near a neutral pH value as a result of selective dissolution of either ZnO or PO_x.
