In this paper, we sum up the improvement of the Sn-Sb-Co oxide coated titanium metal anode.

The defect and energy level effect of antimony-doped tin oxide were discussed with possible defect reactions for the conductive powder.

A comparison has been made between systems of stannous oxalate and antimony trioxide, the result shows the former has a bright future as a polycondensation catalyst in practical production.
