The initial oxidation of Zr1Nb alloy in oxygen, water and hydrogen peroxide at room temperature has been studied by angle-resolved X-ray photoelectron spectroscopy. The clean surface of alloy has been prepared either by scraping under ultrahigh vacuum or by argon ion sputtering. The four well defined oxidation states of Zr were identified in the oxide films on Zr1Nb. Mathematical analysis of the fitted Zr3d spectra based on a layred structure model allowed us to estimate the thicknesses of individual suboxide layers. The presence of zirconium hydride was observed in the spectra of Zr3d electrons of the samples oxidized by water.
