Title:
ALLOY MATERIAL
Document Type and Number:
WIPO Patent Application WO/2017/038715
Kind Code:
A1
Abstract:
The purpose of the present invention is to easily provide a p-type thermoelectric material that is light with high thermoelectric characteristics. Provided is an alloy having magnesium, calcium and silicon as constituent elements, characterized in that the atomic ratio of the elements constituting the alloy are, when the magnesium, calcium and silicon content are each set as Mg, Ca, and Si, 0 atm%≦Mg/(Mg+Ca+Si)<50 atm% 10 atm% ≦Ca/(Mg+Ca+Si)≦70 atm% 20 atm%≦Si/(Mg+Ca+Si)≦60 atm%, and the oxygen content in the alloy is 10 atm% or less.
