THERMOELECTRIC CONVERSION MATERIAL, THERMOELECTRIC CONVERSION ELEMENT AND THERMOELECTRIC CONVERSION MODULE
To provide: a thermoelectric conversion material which is composed of a sintered body that is mainly composed of magnesium silicide, which is excellent in oxidation resistance, and which can configure a thermoelectric conversion module excellent in thermoelectric conversion efficiency; a thermoelectric conversion element using the thermoelectric conversion material; and a thermoelectric conversion module.SOLUTION: A thermoelectric conversion material is composed of a sintered body that is mainly composed of magnesium silicide. The thermoelectric conversion material is characterized by having a magnesium silicide phase 12 and a magnesium oxide layer 13 that is formed in the surface layer of the magnesium silicide phase 12, while being also characterized in that: an aluminum enriched layer 14 that has a higher Al concentration than the inner part of the magnesium silicide phase 12 is formed between the magnesium oxide layer 13 and the magnesium silicide phase 12; and the aluminum enriched layer 14 has an aluminum metal phase 15 that is composed of aluminum or an aluminum alloy.SELECTED DRAWING: Figure 2
【課題】マグネシウムシリサイドを主成分とする焼結体からなり、耐酸化性に優れており、熱電変換効率に優れた熱電変換モジュールを構成することが可能な熱電変換材料、及び、この熱電変換材料を用いた熱電変換素子、及び、熱電変換モジュールを提供する。【解決手段】マグネシウムシリサイドを主成分とする焼結体からなる熱電変換材料であって、マグネシウムシリサイド相１２と、このマグネシウムシリサイド相１２の表層に形成されたマグネシウム酸化物層１３と、を有し、マグネシウム酸化物層１３とマグネシウムシリサイド相１２との間に、マグネシウムシリサイド相１２内部よりもＡｌ濃度の高いアルミニウム濃化層１４が形成されており、アルミニウム濃化層１４は、アルミニウム又はアルミニウム合金からなる金属アルミニウム相１５を有していることを特徴とする。【選択図】図２
