XRD and SPM techniques were used to identify the products and reaction rates for CuCl oxidization. The results showed tbe reaction between CuCl, O_2 and H_2O is rapid at ambient conditions. The bronze powder-corrosion with Cu(Ⅱ) formed through the corrosion with Cu(Ⅰ) such as (CuCl), as soon as the Cu_2(OH)_3Cl once formed, Cu(Ⅱ) ion occured in the mean while; the fresh corrosion products dispersed in solution as colloidal dispersions, and CuCl transformed into Cu_2(OH)_3Cl through Cu_2O.
The experimental phenomena were discussed. The reaction order, reaction rate, and apparent activation energy of these reaction were calculated.
