Effect of dielectric gaps on the conductance of resistance composites

Conclusions Mathematical expressions are given describing the contact resistance of the dielectric gaps in resistance composites and its temperature dependence. It is shown that thermally stable composites can be obtained by ensuring that the thermally induced changes in the resistance of their conducting particles are counter balanced by those of their gaps. Theoretical relationships between the CTE of the binder and conducting components are established which are necessary for the formulation of thermally compensated systems.Translated from Poroshkovaya Metallurgiya, No. 4(208), pp. 85–89, April, 1980.
