Electrochemical determination of diffusivity and the solubility-diffusivity product of oxygen in internally oxidised copper

Abstract

Diffusivity and the solubility-diffusivity product of oxygen in internally oxidised copper containing 0.22 wt% magnesium is determined by both potentiostatic and potentiometric techniques with the help of a single galvanic cell in the temperature range 750-1000°C. Internally oxidised magnesium oxide phase is found to have negligible effect on the diffusivity values. © 1981.
