Abstract
Three different thick film printing paste compositions were
prepared by mixing ruthenium dioxide with Pb0-Mg0-
Ge02 glasses in such a proportion so as to maintain a
constant volume ratio and by addition of an appropriate
amount of organic vehicle. The pastes so prepared were
printed on alumina substrates, dried on a hot plate and
fired. Ohmic resistance and T.C.R. were measured.
It was observed that T.C.R. was closely related to the
relative coefficient of thermal expansion of the glass and
the ceramic material of the substrates.
