Abstract
Apart from superconducting materials below their critical transition temperature, all other materials subjected to a temperature gradient will develop an electromotive force or (absolute) thermopower which is itself a function of temperature. We have discovered that the thermopower of Ti3SiC2 is essentially zero over an extended temperature range (from 300 to 850 K). This material should allow the thermopower of other substances to be determined directly at high temperatures, a measurement that has so far been impossible.
