Abstract
We have studied the effect of preparation procedure, crystallite shape and size, and oxidation conditions on the oxidation behavior of silicon micro- and nanopowders. The oxidation process is shown to occur in two steps, with a transition at a certain thickness of the oxidized layer, which depends on the oxidation time, particle shape, and particle size. The composition and physicochemical properties of the oxide films have been determined in relation to the shape and size of the silicon particles. The results indicate that the silicon micro- and nanopowders differ in oxidation mechanism from single-crystal silicon.
