Abstract

Abstract Direct measurements of the Thomson heat of lead have been made from 300 to 600 K, extending the author's previous work (Roberts 1977) from 0 to 350 K. Direct measurements for copper from 300 to 850 K make possible a convenient high-temperature scale which is shown to be more accurate than earlier scales. Thermoelectric measurements have also been made to provide compatible scales for gold and platinum. Deviations from the tables of Cusack and Kendall (1958) range from about – 0·1 μ V/K to + 0·8 μ V/K. Values from Rudnitskii (1956) are found to be in much better agreement with our scales.
