ABSOLUTE THERMOELECTRIC POWER OF Pb–Sn ALLOYS

Abstract

In this work, absolute thermoelectric power (ATP) of Pb , Sn , Pb -20 wt.% Sn , Pb -40 wt.% Sn , Pb -60 wt.% Sn , Pb -80 wt.% Sn are measured. Measurements are performed in a temperature gradient furnace from 20°C to 500°C, for both solid and liquid states. Temperatures are measured with T-type copper-constantan thermocouples, while voltage signal between copper electrodes of those thermocouples is recorded in order to calculate ATP of the sample metal.
