PROCESS FOR MANUFACTURING THERMOELECTRIC MATERIAL, THERMOELECTRIC MATERIAL AND THERMOELECTRIC TRANSDUCER

摘要

A process for manufacturing a thermoelectric material composed of multiple phases which are formed from a supersaturated solid solution through phase separation, characterized by comprising: a step of subjecting a starting material that has been prepared so as to exhibit an abundance ratio deviating from that of a compound present in the equilibrium state to mechanical alloying to form the supersaturated solid solution; and a step of subjecting the supersaturated solid solution to hot pressing and, occasionally, heat treatment to conduct phase separation and solidification.
