Abstract

This work is focused on the characterization of thermoelectric reference materials with traceable Seebeck coefficients in the temperature range from 300 K to 900 K. The presented measurement system will provide a relative uncertainty of the measurement of the Seebeck coefficient of about 5 %. The Seebeck coefficient represents an important component of the figure of merit ZT and thus the low uncertainty of the Seebeck coefficient will also lower the uncertainty of the ZT value. We also present data which lead to the launch of the certification process of a NiCu-alloy according to the ISO Guide 35.
