ABSTRACT:
This invention relates to a method of manufacturing thermoelectric material which has the steps of quenching a thermoelectric alloy in a molten state at a quenching rate higher than 10.sup.3 .degree. C./sec into a membrane or powdery form and subjecting the membrane or powder to cold-forming or sintering. The thermoelectric alloy is a Bi--Sb series alloy having a composition represented by
