Abstract

In the given work, the formation mechanism and kinetics of nano skin obtained on the super-pure (6N – 7N+) gallium melts surface during oxidation in air at temperature range 20 – 100°C is studied by methods of TG, SEM–EDX and AES. It is shown that, as a result of penetration of oxygen atoms (released by dissociative adsorption) in the layered subsurface with 5 – 6 atomic diameter thickness, transforms to amorphous gallium oxide elastic skin, such as continuous nanoshell of equal thickness ( 15 Å) on the whole surface of the melt. The growth of the mentioned oxide skin thickness formed in the first seconds, obeys more retarded linear kinetics up to 100°C, and after few hours its thickness reaches  50 nm. Further oxidation process in the atmospheric condition at room temperature practically stops.
