Document Type and Number:
Japanese Patent JP3572814
Kind Code:

Abstract:
PROBLEM TO BE SOLVED: To provide a method for preparing thermo-electric refrigerating material which can improve a performance index Z. SOLUTION: Material containing one or two selected from the group of Bi and Sb and one or two selected from the group of Te and Se is liquid- quenched into a thin film or powder, which is further ground into powder 1. The powder 1 is solidified and molded by sintering the powder through discharged plasma under such a condition that grains in the powder 1 will not be made too large. The powder 1 can be solidified and molded when the powder is subjected to the electrical discharge plasma sintering process under conditions of 150<=T<=300 and -(9×(T-150)/500)+3<=P or under conditions of 300 ).
