Conductivity of Oils and Waxes

Subjects

Abstract

A FEW years ago I detected a curious region of negative temperature coefficient of the conductivity of heavy oils, namely, a rising conductivity with decreasing temperature1. It occurred in the neighbourhood of the solidifying point. A similar phenomenon has recently been observed by W. Jackson with paraffin wax2, just below its melting point. The effect is thought to represent probably a characteristic of both oils and waxes, at least of those containing hydrocarbons. It seems therefore desirable to put forward a theory to account for it.
