Abstract

Small Cu2O cylinders were oxidized in a TGA apparatus in air from 850 to 1000 ºC. The activation energy for the oxidation kinetics of the cuprous oxide in the temperature range mentioned above was alsoestimated. Cuprous oxide oxidizes according to the cubic law; such kinetic law is explained in terms of the defect concentration within the Cu2O crystal structure.
