Abstract :
The synthesis of nanoparticles (ZnO)n was found out at study of liquid zinc (Zn)L oxidizing by supercritical CO2. This process called as chemical recondensation (CR). It was determined that depending on CR conditions the nanoparticles with size of 5-50 nm and the nanoneedles with diameter of 25.100 nm, length of up to 50 mum are synthesized. For CR of (Zn)L in CO2 the cluster mechanism is suggested and kinetic parameters are estimated. Besides (ZnO)n at zinc CR in CO2 carbon and CO are formed.
