The regularities of changes in structure and morphology of Zn nanosystems with network morphology have been investigated during their oxidation in air atmosphere.  The nanosystems phase and elemental composition have been analyzed on different stages of their gradual oxidation. It has been shown, that transition from slow to fast initial heating of the nanosystems up to the temperature of their full oxidation 350 °С suppresses nucleation of new ZnO crystals on the nanowires surface. The mechanism of new ZnO crystals formation is explained by thermal diffusion processes that appear due to  the nanowires low thermal conductivity, by developed defect system and also by possible cracking of the nanowires surface during the oxidation process.
