The nature of exothermal and irreversible structural changes observed during linear heating of nanocrystalline ZnO powders was investigated using differential scanning calorimetry, X ray, SEM and TEM analysis. Nanocrystalline ZnO powders were obtained by ultrasonic spray pyrolysis of 0.8 mol/dm(3) zinc nitrate solution and subsequent decomposition of 2.7 mum sized droplets in the temperature range up to 600 degreesC, F-air = 1.2 dm(3)/min. Produced particles are characterized by uniform and submicronic size, BET = 4.94 m(2)/g, high phase purity and granular or circular "open" surface as the consequence of primary crystallites presence with average size of d = 20 nm. The observed quasi nucleation-growth process during heating of this powder was discussed in the terms of primary crystallites structural changes.
