Abstract
A tin oxide-based electrode formed from a composition including a majority component comprising tin-oxide (SnO2), and additives comprising CuO, ZnO, and a resistivity modifying species. The total amount of CuO and ZnO is not greater than about 0.3 wt %, and the ZnO is present in an amount within a range between about 0.1 wt % and about 0.19 wt %.

A tin oxide-based electrode formed from a composition comprising:
- a majority component comprising tin-oxide (SnO2);
- and
- additives comprising CuO, ZnO, and a resistivity modifying species, wherein a total amount of CuO and ZnO is not greater than about 0.4 wt %, and wherein the ZnO is present in an amount within a range between about 0.1 wt % and about 0.19 wt %.
A tin oxide-based electrode formed from a composition comprising:
- a majority component comprising tin-oxide (SnO2);
- and
- additives comprising not greater than about 0.15 wt % CuO, ZnO within a range between about 0.1 wt % and about 0.19 wt %, and a resistivity modifying species within a range between about 0.5 wt % and about 1.5 wt %.
An electrode comprising:
- a tin oxide-based body having a rectangular cross-sectional contour and being free of macroscopic internal cracks, wherein the electrode is formed from a composition comprising:
- a majority component including tin-oxide (SnO2);
- and
- additives comprising CuO, ZnO, and a resistivity modifying species, wherein CuO is present in an amount of less than about 0.2 wt % and ZnO is present in an amount within a range between about 0.1 wt % and about 0.19 wt %.
