THERMOELECTRIC MATERIAL FOR LOW TEMPERATURE USE AND METHOD OF MANUFACTURING THE SAME

摘要

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 103 DEG 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 {(Bi100-xxSbx)100-yxEIIy}100-zxEIz where EI represents a group III or group IV element, EII represents a group IV or group VI element, x represents a number of 5-20, y represents an integer of 0-20 and z represents a number of 0.05-10, respectively.
