Annotation	The formation mechanisms of paramagnetic centers originating from Zr3+ and Cr5+ ions and the influence of the nanoparticle composition on thermal generation processes of these paramagnetic centers were studied in ZrO2 structure by electron paramagnetic resonance. A set of nanosized zirconium oxide powders ( nominally pure ZrO2, ZrO2 doped with correspondingly Y2O3 and Sc2O3, Cr2O3 and Y2O3, as well as Cr2O3 ) was investigated. Annealing effects on the EPR lines of Zr3+ and Cr5+ ions were found to be different. Annealing curves of EPR signals caused by Cr5+ ions have a maximum in temperature range 500–600 oC. Mechanisms of Zr3+ and Cr5+ ions formation were discussed.
