(FR) MATÉRIAU D'ALLIAGE
(JA) 合金材料
Abstract:
(EN) 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.
(FR) La présente invention concerne la production aisée d'un matériau thermoélectrique de type p qui soit léger avec des caractéristiques thermoélectriques élevées. La présente invention concerne un alliage comprenant du magnésium, du calcium et du silicium en tant qu'éléments constitutifs, caractérisé en ce que le rapport atomique des éléments constituant l'alliage est, lorsque la teneur en magnésium, calcium et silicium est chacune définie en tant que Mg, Ca et 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% et la teneur en oxygène dans l'alliage est de 10 atm% ou moins.
(JA) 本発明の目的は、軽量でかつ熱電特性の高いp型の熱電材料を容易に提供することにある。 構成元素としてマグネシウム、カルシウム及びシリコンを有する合金であって、当該合金を構成する元素の原子比が、マグネシウム、カルシウム及びシリコンの含有量をそれぞれMg、Ca及びSiとしたときに 0atm%≦Mg/(Mg+Ca+Si)<50atm% 10atm%≦Ca/(Mg+Ca+Si)≦70atm% 20atm%≦Si/(Mg+Ca+Si)≦60atm% であり、当該合金中の含有酸素量が10atm%以下であることを特徴とする合金。
