Notes:
Ruthenium-based thick-film resistors (TFRs) with lead borosilicate glasses of various compositions have been examined for their electrical properties. A striking increase in resistivity has been observed with lead-depleted glasses, and analysis of this increase reveals that it is derived from the critical loss of Ru ions/clusters in the glass. With high-lead-content glasses, the resistivity decreases by two orders of magnitude, in conjunction with the structural inclination of glass toward PbO·SiO2, 2PbO·SiO2, and 4PbO·B2O3, which are believed to accommodate more Ru ions/clusters. These behaviors substantiate the role of Ru ions/clusters in glass as an indispensable entity for electrical conduction in TFRs.
