Abstract

Abstract:

The oxidation process of pure tin and tin samples doped by Ga, S and Cu with different particle sizes has been investigated by DTA,TG and XRD methods. Results revealed that 0.1%addition of Ga markedly influenced the oxidation process of tin. In the heating process, SnO which presents as a more compact film formed on the surface of the particles protected the particles from oxidation to certain extent. In the other cases, tin oxidized into SnO2 directively. S addition deteriorated the oxidation process and lowered the oxidation temperature.
