Abstract
The oxidation kinetics of fine-grain copper powder produced from gaseo us phase was studied when heated in air at different rates. The sequen ce of the oxidation stages was determined using thermogravimetric (TG) and differential thermal analysis (DTA) and phase analysis. The kinet ics were analyzed on the basic of a well-known method widely used for die study of thermal decomposition in various systems. The limiting st age of the reaction was determined and the kinetic parameters calculat ed.
