| Abstract |
| The effect of bismuth oxide on the sheet resistivity and TCR or
ruthenium dioxide based resistors has been studied. It has been obse"
ed that bismuth oxide decreases the sheet resistivity and shifts
the TCR towards the positive direction. It also enhances the formation
of complex ruthenates and results in much lower requirement or
Ru02 than otherwise found necessary. An excess of bismuth oxide,
on the other hand, may often result in the flow of glass which in turn
will impair the geometry of the print. |
