The present investigation was undertaken to determine continuously the oxygen concentration in molten copper using solid electrolyte cell technique.
The oxygen concentration ranges investigated were 40-2000ppm.
The cells used were as follows;
Pt, Air/Zr02 (+CaO)/O (in liq. Cu), Mo
Pt, Ni, NiO /Zr02 (+CaO) CO (in liq. Cu), Mo.
From these experimental results it was found that the oxygen concentrations estimated by e. m. f. values were good agreement with those chemically determined ones.
Furthermore, the durability of calcia stabilized zirconia solid electrolyte was also investigated.
