Surface alternations of Cr $_{2}$ O $_{3}$ -CoO-Al $_{2}$ O $_{3}$ -doped Iron-Phosphate Glasses containing simulated fission products on heating after water immersion test are investigated. Iron-phosphate glasses doped with Cr $_{2}$ O $_{3}$ -CoO-Al $_{2}$ O $_{3}$ show quite high chemical durability. Valences of iron and doped Chromium ions have been found to play important roles to form water-resistant glass surface from the analysis of X-ray photoelectron spectroscopy (XPS).
