2. 25℃以上の温度で2mΩ・cm以下の電気抵抗率を有する、上記項1に記載の金属材料。
3. n/(x+y)の値が0.45〜0.8の範囲内である、上記項1又は2に記載の金属材料。
4. 六方最密構造を有する上記項1〜3のいずれかに記載の金属材料。
5. 上記項1〜4のいずれかに記載の金属材料、又はその焼結体からなるn型熱電変換材料。
6. 上記項5に記載のn型熱電変換材料を含む熱電変換モジュール。
Mn源としてマンガン(Mn)、Si源としてシリコン(Si)及びAl源としてアルミニウム(Al)を用い、Mn:Si:Al(元素比)=3.0:4.0:2.3となるように原料物質を配合した後、アーク熔解法により約35kPaの減圧アルゴン雰囲気中で原料を熔融させ、融液を十分に混合した後、室温まで冷却して上記した原料成分からなる熔解固化物を得た。
原料の種類又は配合割合を変える以外は参考例1と同様の工程により、下記表1及び表2に示す組成の焼結成形体を作製した。各原料としては、それぞれの金属単体を用いた。
実施例1〜12及び参考例1〜23で得られた各焼結成形体について、下記の方法でゼーベック係数、電気抵抗率、熱伝導度、及び無次元性能指数を求めた。
試料を断面が3〜5mm角、長さが3〜8mm程度の矩形に成形し、Rタイプ(白金−白金・ロジウム)熱電対を銀ペーストで両端面に接続した。試料を管状電気炉に入れ、100〜700℃に加熱し、熱電対を設けた片面にエアポンプを用い室温の空気を当てることで温度差を付け、試料両端面で発生した熱起電力を熱電対の白金線を用い測定した。熱起電力と両端面の温度差によりゼーベック係数を算出した。
試料を断面が3〜5mm角、長さが3〜8mm程度の矩形に成形し、銀ペーストと白金線を用い両端面に電流端子、側面に電圧端子を設け、直流四端子法により測定した。
試料を幅約5mm、長さ約8mm、厚さ約1.5mmに成型し、レーザーフラッシュ法により熱拡散率と比熱を測定した。これらの数値とアルキメデス法により測定した密度をかけ合わせることで熱伝導度を算出した。
