Abstract
Oxide is undesirably grown on the surface of grains of thermoelectric alloy, and the resistivity of the thermoelectric alloy is decreased due to the oxide; however, the oxide is reduced with hydrogen gas before the powder is solidified, and the pieces of thermoelectric alloy produced from the oxygen-free powder achieve a large figure of merit.
